First, welcome to the forum.
There are a few things I can think of. Seeing that you've just started to bowl seriously, I'm going to be honest in saying this. Rather than going to a new ball right now, invest in a coach. This is something that bowlers of all levels will do from time to time, and I have done this. I would rather have you focus on consistency, repeating shots, and learning to work with what you currently have than jumping to a new ball right out the gate.
For example, the person who drills my stuff is also a coach. When I first met her, she had me on the lanes to learn my game (which all good drillers will do) before drilling anything. It turns out that she found a few minor things in my swing/approach that were causing the timing issues I was having. So, by shortening my first step (I take 5 steps) and lowering my backswing a little bit, it really improved the timing and leverage at the line. Once that was fixed, I drilled some new stuff to match my game.
Now, the Meanstreak Brawler is actually a good ball from Brunswick. It's versatile and is designed to be used for medium to medium-heavy patterns. On most house shots, it should be plenty. The Disturbed will definitely be stronger, the Hysteria will be similar, and the Wrecker is more of a medium to medium-light oil ball (though it is stronger than advertised).
Coaching will cost you some money. But, think of it as money well spent compared to buying a new ball and then having it possibly be a dud.
