my advice would be:
go try them all out, and see which one feels better to your feet and playing style
Third on that one.This 100x. We can't tell you which pedal would be best for you, you have to go try some pedals out to see what you like. You may even find something that's not on your list that you like better.
sounds like a bad store then, if they wont let you try them out before buying, if you can, take your business eslewhere i'd suggest. any good store lets you try before you buy in most cases.
