+1. From your description, it does not sound to be "the balls' fault", rather a release and alignment issue - esp. when things work now and then. Lanes could be spotty or oiled unevenly, but a frequent 10 pin is not a ball issue.
One thing to consider, though, is that both ball have a coverstock that tends to float easily through the heads and react very strong and quickly to dry areas. This can cause over/under issues, even with a sanded surface, and bot balls are pretty similar in design, having a low RG core with a considerable mass bias. IMHO not a smart arsenal, chances are high that when one ball does not "work" the other won't, too.
If you want to add a ball (and I do not think that this is the true solution to the prroblem you describe), maybe go for a simple Karma Solid, and maybe hit it with Rough Buff or a 4.000 grit pad. The ball would be very different in many aspects, and esp. react more smoothly to friction with a less violent break point and also less entry angle, which could promote better carry (which should be mended thorugh release changes, though). Just my 2 cents.
