LF Binding fitment comparison

So I am looking at some open toed 9-10 watson's from someone,

so far I've ridden a Lrg. Transit and Lrg. Ultra Suc.

I am wondering, given that every pair of shoes I own are size 9, if these Watsons will fee good ? or too loose.

My general feel with the size ranges for LF (large) is that with a size 9 my bindings are tight as hell, anyone with a bigger foot would be in a lot of pain.

SO I am looking for feedback from anyone that's rocked all or some of these bindings and can tell me with confidence if I should or shouldn't be looking at the 9-10 or maybe the 8-9 ?

I ride the recomended size with liquid force but ive only used the sphynx bindings. They fit great, pretty tight at first but after a while they start to feel like a pillow yet you can tighten them down as much as you want.

O yeah and for reference I have a size ten feet and hyperlites medium are too small and the large were too big for me with the bindings ive tried on.

I ride the 07 Watson OT in a 11-12 and I wear a size 12 shoe. The 11-12 fits perfect. Big toe goes almost to the end of foot bed.
