I found less to be more. My favorite pair is the very first pair I bought. They are a Fox brand, not baggies but regular lycra type shorts. I use these for doubles all the time and they have the least amount of padding of any shorts I have. PI's are a death sentence for me, and the cheap Volers work well too.
But what I've found to really work the best is to have a comfortable saddle. No shorts in the world will compensate for a bad fitting saddle.
