Is it worth it? I like to play blues, rock, and jazz etc. But sometimes I just want to play some virtuoso metal like Steve Vai and Satch and since I don't have a guitar with a floyd rose I'm thinking whether I should augment my strat with this or whether it would be wiser to just get a new guitar with a floyd rose. I'm kind of undecided because I heard this system is better than floyd rose due to the way it's designed.

Here are some video examples:

It looks like a good design, I'm still curious about how that "blade" works. The locknut is HUGE though! If it puts an end to the hour long string changes common to Floyd Roses then I may drop one into my American Deluxe HSS
