Hey Jon,
The Delta 1 being resin still offers a different look and has different reaction capabilities (stronger off dry) than our GP2 which is designed for heavy oil. So it is well understood why one may like a particular ball and drill 2 of them to just handle different amounts of oil or to just get a different look on the same amount of oil.
I just drilled Arsenal Reactive #2 in more of a normal position (pin over bridge, cg out right some) and it is a world of difference from my first one (drilled weak, pin over mid) but I like the cover and core so much, I had to drill a second one.
