A bit of background before the actual question just to put it in perspective:
I ride a 2007 Ride Timeless 161 (I'm 5 ft 10, 75 kg). I got that because although not an expert, I was reaching speeds where board flutter was threatening to kill me everytime it got interesting. Plus it was half price on ebay
I ride groomers, some pow, easy off-piste. Nothing too fancy, but I'm pretty decent on a good day.
Bindings, I got some Salomon SPX 45 from a few seasons back (half-price sale again, what can I say I'm a sucker for last season's stuff). Bootwise I have some 32s, I think Prions, a very decent simple model holding out very well.
I'd love to replace the SPX bindings, they're ok but I get foot pain/fatigue pretty quickly. Plus I find the toeside straps are starting to get loose by themselves nowadays. I'd love something more comfortable and cushy. A couple of years back I tried Burton P1's on another board and they were unbelievably more comfortable, but those disappeared on a bad day.
So my question (sorry for the drivel) is this: does it make sense to put something like the P1's on the timeless, or will the loss in response actually make it harder and more tiresome to drive the board around? I'm guessing the harder the binding, the better the response, and the less work required to get a good line, but maybe that's wrong. I'm nowhere near knowledgeable enough to pick a good binding based on specs, and the choice and tech on the market is mind boggling.
So to summarize, would I be better off getting a well-padded and cushy set of bindings or would that just not make sense on a stiffer board like my Timeless and corrupt the ride altogether?
I'm actually considering the K2 cinch line, quite curious about the rear entry option as I've never tried, although the latest CTX doesn't look like it's heading in the right direction (strap entry made harder). Otherwise if anyone who knows their way around bindings has a suggestion, I'll gladly read up on it.
Thanks a lot.
