Thanks for all the suggestions. I have done a fair amount of research online in the past couple of days and am going to head to my local shop in a couple of weeks as soon as they are fully stocked for the season so i can test a few out with my boots and make sure I get a good fit.
One last question - my most recent set of bindings was Ride SPI (2006 i believe but maybe 2007). Anyway, I liked them although they were probably a bit stiffer than i need. I always had thought of the SPI's as very stiff bindings. However, on the Ride website they have a flex rating of "8" while the Ride Alpha MVMNT has a "7" and the Optimo Contraband has a "6". Both the Alpha and Optimo are listed as freestyle bindings even though they are only 1-2 flex "notches" below the SPI.
I am an intermediate to advanced snowboarder who probably only goes to a park only once a year but I just cant imagine that going from a binding with a flex of 8 to one with a 6 or a 7 would change my riding experience very much. So i guess my actual question is - has anyone moved from a higher flex to a medium flex binding that can share their insight? For someone who does mostly freeriding, will I get frustrated with the incremental flex or will it be a very minor difference? Thanks.
