Some Advice
Jetpilot,
You have an F-100? Whoa. How is the kit? How's the buildability? I never liked the Hun until I saw Kent Nogy's fly at Dixie. Rich Fong has one for the history books (finish wise). What are you powering yours with?
As far as DF setups go, I think the best pipe going is Tom Cook's System II. It's a little heavier than BV's, but it's quiet, and it doesn't have O-rings to blow out. You can get 140 runs out of it before you have to replace the rubber.
