My opinion is based on what type of bowling you will be doing. I cannot view your video so I can't see what your style is. But if you are looking for a 2-ball arsenal (general league bowling), then I would recommend a Sigma Sting to complement your Uproar. The gap between the two is a little larger, but the Sigma Sting will allow you to cover conditions with a little more oil. If you are looking at more than a 2-ball arsenal (some tournament or multiple house bowling), then the Venom Shock would be a good step up from your Uproar with room to add more above that with something like a Covert Revolt or Cruel Intent/Raptor Talon.
Let us know what you decide to do and good luck with whichever ball you decide to get.
It's definitely not just for league bowling. I bowl lots of tournaments, sweepers, pot games in tons of different houses.
I normally keep 6-8 balls in my current arsenal and they are as follows:
Leagues/Tournys w/ house shots: Uproar, Victory Road Pearl, Wrecker
Advance Tournys/Sport shots: weakly drilled Manic @2000 no polish to control the backends, extremely aggressive drilled Reign On
I feel like I'm just missing a true bench mark and a heavy oiler.
If I were staying with Roto/Storm, I was leaning towards the Asylum as the benchmark and a Marvel-S for my heavy oil ball.
I feel like my main 3 overall would be the Asylum, Uproar, and Wrecker.
So a Motiv equivalent to that arsenal is what I'm looking for if I do switch over.
Thanks guys.
