9:1!!!
It's what I'm running (going to run I guess, once built)
It's What Chris at SF is doing,
BurritaSVT is doing it.
We're ALL DOING IT.
Like I said, I think the Ross Ones are great, I don't know how much .5CR will change spool time, how much extra boost you'll need, etc. BUT, it depends on your $$$$. If you have access to the Diamonds, go for it. I know the Ross ones are at Draxas.com, and they're CHEAP TOO!! (comparatively).
both are awesome companies, go with the $$$ factor (Does diamond have to make another set for you?)
