Well im not new to snowboarding but im kinda confused on the diffrence between entery level bindings and high end bindings.
i just kinda think whatever holds your feet in place
also whats the best strap setup for park riding
Dont sweat it. Its just a different feel going edge to edge. The components of a good binding boil down to how stiff/soft they are (totally preference), overall response, how heavy/light they are, durability, comfort of the straps, stance options, and how well the baseplate fits your boot.
Cheap bindings are usually kinda uncomfortable over the straps and dont respond very well and you cant change many aspects of the binding other than the angle and forward lean. Better bindings are more comfortable, more responsive, allow you more options like (and maybe a few more)...
-heel cup length
-finer strap length options
-where the strap connects to the baseplate or heel cup
-finer highback lean options
Better qualaties of better bindings
-better materials and structure
-dynamic fit to your boot
-options of adjustment
the 140 to 250$ range is about where you should look into for pretty good bindings before it just starts to be a little over done (even though 250 can push it in some cases)
