I put the Rico drill in an Equation, a flippy ball by nature. I had a tough time carrying in a local house, was never able to square up the pocket and carry consistently.
My carry percentage went way up because the Rico drill read the midlane better and tamed the backend reaction without losing any power at the pins.
I played around with the drilling in a Heist and it made an even rolling ball even more even. Was really good on tougher, flatter conditions, but did not see much success on house shots.
