Being that they are so cheap for both sets makes me wonder.

What do you guy think?

EDIT I forgot to mention this is for a strictly drag launching setup.

I don't see why not...UPR is a reputable company. That's a good price!

Its a good price but everyone says you get what you pay for. If those will be fine for a drag oriented setup then I'll get 'em
