I have been offered a deal on a new set of Marker Squire binding for $100. Are they a good binding? I am 6'2" 140lbs(ish). I ski park and all mountain, and these will be mounted on my S3's -- they are my only ski, so they go everywhere.
IMO, it's worth it to just put the money into a good binding. Better for your knees, and its more of an investment. Get a good binding that will last awhile without causing any headaches.
I wouldn't get squires, at least get griffons.
2bi4 is lightyears ahead of 4bi9, whens the last you saw someone build a house using 4bi9s? -jfletcher
