I use to say it doesn't matter... I see people have success with all brands. But EVERY time I try another company, or recommend another company for a friend or teammate, it has immediately backfired. I've tried 5 Radical balls, because I've followed Mo for 2 decades, and didn't match up with a single one. I recommended my friend try a Radical ball, and the same thing, it rolled very poorly. I tried throwing it, and couldn't get it to look good either. My teammate was new to bowling, he liked the DV8 brand, so I helped him get fit and drilled for a Pitbull bark or bite, can't remember, and it never reacted well. After returning from Covid I was struggling myself, and experimented with the Motiv Fatal Venom, and I could never get a read on the ball. It felt so condition specific that I could never identify when or why it would work.
For me, my friends, and my teammates, it's the Storm Umbrella 99% of the time and it just works without any hiccups. The only other company I'm willing to consider is Hammer, but they're now owned by Brunswick, so it's even less likely I do it, unless it's a Widow.
It's probably all in my head, but I'm not going to ignore my own experience and results, or those of the people closest to me. Maybe it's alley specific, who knows. Global 900 seems to be the most impressive brand on the market right now, I'm not sure if Storm just got lucky with the acquisition, or it's the combination of the minds to create what they have, but regardless, the balls they've dropped over the last 2 years have been absolute winners. The Zen, Reality, and Wolverine are probably the most complete arsenal (universally successful\versatile) top to bottom that any company has created, as long as I've been bowling.
Also, I'm a sucker for the scent gimmick.
Motive's logo system is the best. I dislike engravings.
Brunswick Dot technology is brilliant.
I'm not sure I believe in dynamicore, but it would be nice to have it just in case.
The perfect ball would be a combination of a Global 900 Core, Storm Cover\scent, Swag coloring, Radical filler material, Brunswick Dot technology, and Motivs laser logos.
