Test 3 was done with simply undoing the peep tube and leaving the 1/4" peep on the string whichnetted 1 fps.

I'm not sure exactly how much weight I'll be saving but as soon as G5 sends out their 5/16" peep (new unreleased product)to their vendors, I'll be ordering one. Hopefully, and I'm thinkingthat'll free up 4-5 fps over the current bulky tube style setup.
