The truth is that the huge majority of riders simply don't care what pedals, or anything else for that matter, that you care to use.

There is a minority that is definitely going to laugh at you. I know this for sure because they find a reason to laugh or criticize absolutely everybody. Bike's too good or not good enough. Jersey and shorts mismatched or everything is too matchy-matchy. Too many spacers in the stem, wrong handlebar tape, wrong water bottle cage or even (gasp) a camelback. Don't let them catch you using the big chainring/big cog combination. You get the idea. Just don't take it personally.
