On an average, I'd have to say the Freakazoid. However, personally I have been encountering a fair amount of oil and with the versatility I can get with my GP2, it's the first ball out of my bag. In 4 weeks, I've been able to put up 2 700's in the same house (which changes) but this tells me what's working for me there.
