When you say little axis, do you mean tilt? little to no tilt means you need the ball to retain its energy for a good skid-hook-roll phase. Polishing the Invasion would be the quickest, and cheapest way to help it retain more energy.
The next alternative is to plug and redrill weaker or go with lower end equipment. IMO, the best thing to do, though time consuming is to increase your tilt(open the hand up some). Until recently, I could really only use low end equipment on any pattern, even the PBAX patterns.
One night recently messing around, I tried a few shots with my hand "broken" instead of the moderate cup I used to do. I immediately was able to move 10 boards right because of the increase of skid. The midlane read and back end were not sacrificed. Try it in practice one day.
Lastly, keep in mind that you still have to follow through or it will do nothing but skid.
Oh, the question about pearls. I for one love pearls, and some of them are quite strong. The prodigy for one is an extremely aggressive pearl that is stronger front to back for me than the Gravity.
