Hey Brian,
I didn't want to hijack Rocks thread (he's a big guy..
) in case anyone else had some input for him. Here's what I'd suggest based on your info...
Heavy - Phenom (consider an Animal for real heavy stuff, if needed)
Med/Heavy - Unleashed(if Phenom is there), Untamed/Rule (if Animal was there)
Med/med - Mutant/Havoc/FreakaZoid
Med/Lite - Freakout/Sheer Havoc
Med - Threat
Med/Dry - Dry Heat/Crash
Dry - Col Scout/Col Fear(more backend for 3 piece)
Spare ball - plastic/ or whatever works..
Strider makes a good point that the Havoc is too strong to be considered a med/dry ball. Not sure if yours is polished or not but most of us had that ball hooking a lot more then expected. I have placed the 3 new balls above in their respective categories based on early feedback and design. I haven't personally thrown them yet. Hope some of this helps....
