Hey Big,
Interesting, I drilled my Untamed with the mb at 2.5 so it rolls very early and even, not touchy at all. The Slash is a very versatile ball that simply reacts to the layout that's placed on it.
In the case of the Untamed, like Traumabill states, it does have a lower rg combined with my short mb to pap, it helped offset my high tilt and produced a very nice roll. This may be your problem, that if your rolling too soon and the ball is not storing enough energy for you downlane.
If you can give us the layout of the ball, your pap and some of details of your game, we can maybe help suggest another pattern for you on that ball that would give it a better look.
