.6mm seat stays 58cm frame

Seeking opinions or experienced observations of using .6mm x 16mm(True Temper) seat stays on a 58cm frame. It will be set up for general club riding and some go faster sessions on the road. Rest of frame is 7-4-7 tubes from Columbus. I have the seat stays so I can save a few bucks by using them.

Wondering if the thin tubes will affect handling or hard drives on the pedals.
