I have the big deal and big rig.the big deal is for heavy-medium,very rolly.the big rig I have'nt had much luck with but my best was on med-light wall shot or when the shot breaks down and you want something that clears the heads well with big backend.it has a weaker cover than my intense inferno.for heavy to med.I would go with the big deal and for medium I like the high rev or go with a hawg wild.

I'm not bad,I just bowl that way.
