I think that you're better off to make sure the guitar plays properly and cleanly, when adjusting that A string. It's far more important that the string plays properly than the amount it bends up with the bar.

No no and no

I felt like I was going to need 2 claws on the back for the A string become the way Carl intended. The angle just cant do it. So I kept as it was since it was playing like a dream.
Now I dont mind about GASsing for a Callaham bridge anymore, since I see no point on getting it for my stock bridge working flawlessly.
On the American Standard with 2-Point trem this method was not needed, since it behaved already as supposed to be.
This method is good for those ones with cheap bridges and zinc blocks, that you cant put it to paces, most of the time it will work like a charm. But be aware guys of putting NEW STRINGS on it first and STRING THE GUITAR PROPERLY first.
Aldo my Highway One got a steel block, it was going out of tune slighly with bends and arm use. Now is 440 dead on every time.
In the end of the night I was bored up about setups, so I cleaned up my Highway after putted it to its paces, grabbed my brazilian mahogany dreadnought and played the heck out of it!

Cheers!

Thanks again nikininja for all your support!

See, that's more proof of why I'm skeptical of statements about a Strat staying "perfectly in tune" with whammy use. There seems to be just a little exaggerating about the tuning stability. Claims of perfection, followed by ways to further improve stability? If it was already flawless, then how did bypassing a string tree make it even more flawless? And, I am skeptical that a different bridge block will help tuning stability at all, it makes no sense whatsoever. I see it over and over, "oh, it's perfect", but then when they are tuning up after whammy use, the statements changes to, "well, ...yeah, ...um, it's just a little out of tune." or "it's because the saddles move" or whatever the excuse is. I have yet to see a Strat with a 6 point bridge that stays "perfectly in tune" with whammy use, it just doesn't happen.

Maybe I have a different definition of perfect and flawless?

You´re right shimmilou!
Here´s my exact feedback after this adventure:

I´ve tried both Carl´s and Fradua´s methods:

Fradua: Only usable if you set the tremolo flush with the body, cause with that method if you go upwards with the tremolo it goes out of tune in a glinch. But if you set it flush you can use the trem downwards as you wish and it will not go out of tune, but then again if you bend a string, goes out of tune again. Unusable method for me.

Carl: After much time on really learning how to do it right, and feeling what the guitar was asking on its balance, its very nice indeed. I can go up and down with the tremolo vigorously, double stop bends and it comes back in tune, with the bends comes back exactly in tune, upwards too, only with downwards tremolo use it comes back just a little bit slightly flat, but really imperceptible to the ears, only on the tuner you get to see a slight flatten when using down, like if its 440hz in tune it comes back 435hz, but then you bend something or push the tremolo upwards and its spot on in tune again. Very very usable method Carls described. Never going to flush a trem again.

Yeah, the best that I've had with a six point bridge was with the bar removed, using the heel of my hand for vibrato, only pushing down, it stayed in tune very well. But insert the bar and push down, all strings would be slightly flat while still in tune with each other. Pull the bar up, and the strings return to pitch. I am going to have to make a video, or power point presentation with a large model of the Fender six point bridge, to show that there is no pivot point whatsoever, not the screws nor the plate, and there is no precision with such a setup, and tightening screws, adjusting the claw, only two string wraps on post, lube, etc, all help, but it is never "perfect." It seems so obvious in my mind, but I'm not very good at explaining why it is absolutely impossible for any six point bridge to stay in tune with whammy use. This is confirmed by the same people that claimed "it stays in tune" then state that "yeah, it doesn't stay in tune", with the "Joe Player" or whatever method of setup.

I am reminded of a computer anaolgy, where the advice was given that an upgrade to WMP 10 would result in "perfect" operation, without the problems of WMP 9. After the upgrade I pointed out the problems only to hear, "well, yeah, it does that"...... Ever hear those that claim to have no problems at all with Windows? Yeah, right!

I never bought that pivot thing on 6point either. The way I see it the screws only serves to hold the bridge plate on its place, so it wont lift up the front of the plate when using the tremolo. To me what does make sense is a well cut nut properly lubbed, no string trees, and a proper string to springs balance on setup. I´ll try to fine tune it a little more today, see if I can find where is the problem with the slight flat pitch when returning from a downward trem use, despite its not really a issue to my ear, I´m too a perfecionist guy.
Regarding the setup, I must remember that I´m already pretty much happy for the results, being this a stock Highway Strat, despite of others say, my "cheap ping tuners" are working very well! They only need a little tight up on the top screw and your all there.
