I'm not running this years Autos. I had a pair of 07/08's that worked great, I now have a pair of 08/09 regular autos. I've been riding for 9-10 years now, mainly groomers. Little to no park.
The T1's were a little big for the the 08's but seem to fit fine in the 09 bindings. Size 12 boots, XL bindings. I didn't like the chinsey looking toe strap on this years autos and the ankle strap was revised to cut weight and doesn't look comfy at all. There is barely any padding.
