Many of the people around here liked their Ultimate Inferno after we put a little polish on it, but was too early without. The Absolute was great, and the Vapor Zone was even better. Those two shared the same cover as I recall.
The Intense looked cool (bright colors) going down the lane, but was not as versatile as the above mentioned Absolute and Vapor. The Intense was much more over/under for sure. Blazing Inferno was pretty good for straighter lines as was the Smokin" Inferno. The Scorchin' and Total Infernos never had the "wow factor" with me, but were good for honor scores, so I remember them fondly.
It's always fun to hear others' ideas on certain balls looking back. As time goes by we remember the ones that were favorites, and others that turned out to be less...
And sometimes we start out with a ball and think it's going to be good for the arsenal, but then don't use it as much as the more versatile ones and they end up in the "not good" category. I can remember a few that were not keepers, but didn't notice it until time passed and I analyzed why I never threw it in the bag for "league night". The Twisted Fury solid was not a good one for me, but early on I thought I'd use it regularly. The "test" of time, I guess.
