LL:
I have a few comments, and please understand these are intended to help you and minimize frustrations.
1) I don't believe your layout is a 6" x 4". While I can see you track high, that pin position would make your horizontal axis coordinate something like 6-1/2".
My advice: Never let any pro shop drill another ball for you without them knowing your PAP,physical game, and what you want out of the ball. It's unfair to you to plunk down that kind of $$ to not understand what your stuff is intended to do. They need to be better at helping you on this.
2) I don't think that your game is suited for sending too far away from the pocket in a "swinging" fashion. You thumb the ball down at the release and you are past the leverage point when the thumb comes out which makes your ball track higher. Meaning your stuff reads the front, not the backs, forcing you to play straighter. Even if you had the most whippy ball available, you would get enhanced motion, but not like others get who you bowl with.
My Advice: PM me and I'll give you a trick I use on my students that helps get them to track lower (in this scenario). When done correctly, you'll do less work and get more out of the ball.
