I agree with Niki....I smile when I read these posts (not that I am making light of your question or making sport with you), but I have never used a measuring device for setting the saddles for the curvature of the neck. I have set up 100's of guitar's and each one I just rough in the saddles seeing the type of curve the neck has. I make sure the truss rod is set (I use to do this with the feeler gauge, but have done so many now, I do it by eye). Then I lower the strings till I get buzzing when I play and then start working each one up till the buzzing is gone.

I like my strings LOW, but like Niki is saying, each person has different tastes. Like SRV, he had his strings up really high so he could grab them better playing blues. It just takes time and patience to learn how to do it. When you do it by feel and get the buzzing out all the way up the neck, the guitar will play great. I always found those gauges only would get me 80% of the way there anyhow....Play with it and don't be afraid...it takes some time but once you get it down, you will marvel how easy it is.

The radius gauge (or whatever they call it) has been featured on the cover of the last two StewMac catalogs.

I use a ruler and go by Fender spec guideline. Works for me. Course I play 10s. Lighter or heavier gauge strings will need adjusting from there. It's all preference. The radius gauge could be helpful if I was setting up guitars professionally. It would probably save me a bit of time. Since it's not (yet) a business for me, I prefer to use a ruler. I used to do it by feel as well. Nowadays a ruler and a good pair of glasses works well for me.
