Is there a major difference between the standard, flex, and shock?
Babs, for the most part, the technical difference between the three are the height they raise your bindings off of your board(10-20mm). The point of these things is not only shock absorption on stomps and high speed stability, they also act as a physical leverage increaser between you and your board. Depending on what you want to do with these in your setup whether for race or backcountry or park, i'd just go with the shocks, i use them in the park and for off piste stuff, and i feel like the extra 7 mm gives a comfy bed when you pull those massive stomps and at high speeds, its feels like your riding in a B with wings over the wheels. Hope this helped, adios!
