I drilled the Eruption Pro with my typical symmetrical layout for me, which places the pin about 4.5" from my PAP, next to my ring finger. The CG is stacked below, and the ball does not require a balance hole. I drilled both finger holes to a normal depth, and I left the ball in box finish.
The Eruption Pro uses a higher RG, lower differential version of the popular Resurgence core shape. The RG is raised to 2.50 and the differential is lowered to .035. This core shape has rolled excellent for me in virtually every cover that it has been used in, from oil-hungry covers such as the one used on the OutBurst and Resurgence, to longer, skid-flippy balls such as the Eruption and Momentum. The cover is a brand-new formulation for Columbia 300, designed to get through broken-down heads with ease. It is finished at 1500 with a slower-speed application of Powerhouse Factory Finish.
When I looked over the specs for this ball and listened to the team at Columbia 300 talk about this product, I kept hearing how good this ball would be on burnt heads and broken-down conditions where getting the ball through the front of the lane has become difficult with other products. Given that I like to throw the ball relatively straight, my first thought was that I generally don't have trouble getting the ball through the front of the lane...products such as the original blue Eruption, the Freeze Hybrid, and the Violent Eruption all got through the heads with ease on virtually all conditions for me. If the Eruption Pro gets through the heads even cleaner... would I see the ball float through the midlane as well, thereby giving me an erratic downlane motion, or no motion at all? Would I throw it through the pindeck before it thought about hooking?
Thankfully for me, not only has the Eruption Pro been a usable piece for me, it has quickly become one of my favorite pieces. It does get through the heads better than the Eruption, the Freeze Hybrid, and the Violent Eruption, but it also makes a more consistent move downlane for me than those products, which have all worked well for me over the last couple of seasons. The best way for me to describe it is that I always felt that I had good options on drier lanes... now I have a GREAT option! The motion is very predictable, and it doesn't jump immediately off of friction. It hooks quite a bit downlane, but it is a motion that is easy to adjust and easy to line up with. The carry is phenominal, and with the bright orange color, it's easy to get noticed when throwing it. I have heard more remarks and comments on how well this ball looks than virtually any other product I've thrown in the past, and there are times that I've heard how good it looks at times that I feel like I'm throwing it awful! I have thrown it with success on a multitude of lengths, anything from fresh patterns in the 32-37' range, to broken-down conditions up to 44'. I especially love it on wood surfaces, because it feels like no matter how beat-up the heads get, the Eruption Pro will get through it.
I would recommend the Eruption Pro to any slower-speed bowler that needs help in getting the ball down the lane. It will also roll well for higher-rev players that need a ball to give them a consistent read of the midlane later in events, especially as they chase a pattern inside. As for me, I plan to continue using it every opportunity I have... if I think it has a chance to work, it's coming out of the bag!
