My advice is... you can go as cheap as you want on the pegs, but don't go cheap on the clamps (1 1/8").
Kuryakyn quick clamps are good.
But the cheap clamps with lots of bolts on them do work, but degrade quickly.

Pegs without rubber are slippery.
I sometimes put my feet over the pegs, and rubber padding is easier on my Achilles tendons.
