I have a TF Tuned serviced Float RLC 100 from 2004, and a 2011 Talas 32 150 RL FIT.
You’re absolutely right, I think the Talas has significantly less small bump sensitivity. It’s not that it is particularly jarring, or poor, it certainly doesn’t feel like it’s sticking, but it never has the buttery smoothness of the old Float.
Obviously it’s hard to be sure how much it the 50% extra travel and how much the innards, but It handles high speed big hits so much better though. PLaying in the Dolomites this summer we were mid pack with guys on 180 mm bikes, and it only really got out of its depth once on some very high speed, very big braking bumps. Other than that it was impeccable. On balance, given the adjustability is useful for climbing, I’d recommend it.
incidentally I’m sure the manual says that the spring rate is adjusted for travel, and to set it up at 150 as it automatically adjusts both sag and rate when down to 120. Worth checking though.
