Floyd rose an/ abd Schaller) introduced a new arm model . Screw underside is bigger=a unique whole piece Colider with a hole for exascre driver , instead than the 2 piece cilinder+exa screw we have had from decades .
Is it better ? YES!
it solve the "little wooble " play we have on arm? NO .
I had great hopes and got mislead-ed by enthusiastic Review...
TAKE THE "PUSH -IN" ARM , THAT SOLVE the "wooble" . i have 4,,,
did wait more than 4 months hoping to get the best of 2 worlds ( scre tension and no play) .I learned my lesson. never believe hype .
( Ps:i made sure to "soft "hammer on in the piece into base , so is the natural play of the arm ) , is exactly like my 10 bucks after market arm .. make you a favor and try the push -in instead if you do not want "wobble" arms..
