Between the Fischer FR17's? No... They are still neon green, but they have slightly different looking logos on them. The 05-06's have a Nike "Swoosh" type thing on them. Pretty much identical though. The Freeflex plate is the same.
The new Fischer X17's are different though... They have the same dark grey non-skid paint as the X14's, but the FR17 DIN rating, and no lifter.
