wilkinsons are the best nonlocking 2 post trem on the market. in a trio with a graphite nut and some locking tuners, you have a near locking trem killer. when installed correctly, these trems have killer flutter and are very responsive. not as much as a floyd due to the shorter baseplate, but alot better than any other strat type trem. scoops and other trem tricks are easily done with it, too. i am debating actually buying one from carvin or fishman to retrofit my rt650. excellent value and less headaches than a double locker. i personally would rather own a double locker(lo-pro), but if it HAS to have a strat trem, the wilkinson is the king of that jungle.
BTW, the only wilkinson's i have played were on brian moore's. if brian moore would get off its dead ass and come out with a USA model with a FRO instead of those korean FRL like on the i series, they would have a damn good market.
