Clint-
I agree with most of what you said. For the great majority of my bowling on tougher patterns, I stay away from anything that is skid/flip. I look for two things in my tournament arsenal: excellent carry and controllable reactions.
However, I have had success using asymmetrics on a couple of the new PBA patterns this year, specifically my GP2 (Pin above and right of ring finger, MB 1" right of thumb). The East used the two longest patterns on synthetics, and both conditions seemed to play extremely long and tight for the straighter players (myself included). If you didn't have above-average revs, you had to play very direct. For myself, with my GP2 in box condition, there was enough volume to get the ball through the heads, and the drill pattern provided a strong arc at the breakpoint, with the ball providing phenominal carry. I cashed and made a finals in two tournaments so far with this ball.
With that being said, I do use symmetrical equipment most of the time. I like my CrunchTime and Slash (Slash being slightly polished), and I have had a lot of success throwing a couple of Ebonite V2 Pearls. I also have a Zone Classic that works well at the end of tournaments, but basically as your asymmetical equipment is set up, it has the MB under the thumb, providing a very smooth move at the breakpoint for me.
As a last thought- Track seems to be fairly popular in our region. It's not uncommon to see a Rule GP2 on racks for the longer patterns, and there are a lot of Slashes carried by members who are not under contract.
