Thanks a lot, guys. I was fully expecting to get flamed because this topic must have been discussed previously. But the search function is not so great and stuff changes from year to year.
You convinced me to get the gear instead of waiting a full season. I'm pretty set on La Sportiva Lo5 and Dynafit ST bindings. Not ultra-light, not super heavy. Hopefully it works out. Speaking of ultra light, some of you might be interested in this: http://www.geartrade.com/item/370363/la-sportiva-rt-binding
Finally, REI should be good enough to mount the bindings, right? Or do you have any strong recommendations?
