Hello,
Ok I have two balls,
Storm Spit Fire and
Ebonite Maxim.
At first I was playing with
Ebonite Maxim, I was playing 4-5hours per week, for about 2,5-3months. And ball after this time looks very bad where fingertips are:

After these 2,5-3months I started playing with
Storm Spit Fire. I also was playing a lot, 4-5hours/week. And again after ~3months my fingertips looks like that:

Spit Fire looks better but a little piece of ball is missing near ring finger fingertip

So my question, Am I throwing bad or what? Why there are so many cracks near fingertip?
When balls comes it has oil stripes near middle finger fingertip(in left side), but stripes never goes through fingertip. So from where these cracks comes?
I played only 3months with ball, so I should change 2-3 balls per year?

It's veeeery expensive...
PS. What you thing can I still play with Spit Fire? I'm a little afraid if I will throw a ball on the lane and it will split to few piece

Thanks.
