FKS/turntable binders are the best bindings out there, and also some of the worst.
Pros:
- never pre-release, and if they do, it just means the forward pressure is loosening up, which takes about 5 sec. to fix.
- tightest screw pattern ever, you definitely notice how much livelier the tail is when its aloud to flex properly, VS having binding screws 5 inches behind your heel.
- fairly good release. they are race bindings, so staying in is more of a priority than coming out, but they do have a reliable release, its just a little more sticky feeling than rec. bindings. with some bindings, you never feel it come off. with turntables, the elasticity makes the release a little more prolonged.
- they transmit a ton of energy into the ski, and ski MUCH better than alot of bindings.
Negatives:
- they arnt THAT durable. the important parts are bombproof, but theres alot of little features, tabs, bushings that are always snapped or broken. never really affects performance, but its annoying.
-the brakes suck royal dick. get used to hand bending them back into place. just about every time i fall switch i have to bend my brakes back up.
- that great tight screw pattern is also a negative. on skis without a solid mounting pad or a softwood ski (like alot of K2s), they are more prone to ripping out than some others. ive never had that problem, but they do do it more than say a salomon or something.
- the full turntable heel is SOOOOOO annoying to have to manually reset, and whenever you step them down, half the time the just kick out to the side instead of going down.
all that being said, if the pros of that binder sound good, but the negatives seem like a pain in the ass, get onto ebay and find some of the older look pivots or rossi axial 1s. they are a MILLION times better than the PXs, and have almost all of the same features as the racestock binders. they are wormscrew forward pressure, pretty much indestructible (ive broken more turntables than i have pivots.), and have the BEST release out of any binding ive ever ridden in my life. smooth like butter, and no need to crank dins up real high.
really, the only reason i ride turntables over pivots is that i can score the old ass turntables, rip them apart, and rebuild them for next to nothing, while the pivots cant be taken apart, and they develop a little slop over a few years.
but yea, thats my 2cents
