Jeff,
Great write-up, as usual, on the Rapid Fire. Would be curious to know how yours is layed out.
Probably ought to do a little write-up myself...
My first Rapid Fire is layed out with the pin under the bridge (right around 4 3/4" pin-to-pap for me) with the CG swung out at 45 degrees and a weight hole on midline around 5" from the pin. I first tried this one at 2000 polished and had "this" (hold your arms up in the air and cross them and make a big letter "X", and that's what I had...) reaction, it was not pretty. This reaction was on a lighter volume house shot, as well as a broken down house shot with a little higher volume.
Since this obviously wasn't the reaction I was looking for, I tried a surface change down to 2000, no polish. This is where the ball stands out for me, still gives it decent length due to the longish pin-to-pap, but the surface lets it stand up a bit and still hook in a decent volume of oil. This Rapid still makes the corner and drives through the pins despite being at 2000 abralon...as long as there is some head oil, I can get as far left as I want, feed it to the breakpoint, and just watch it rip back and still drive through the deck.
I liked that reaction so much that I decided to drill a second one this week, pin over the middle finger (around 5 1/4" pin-to-pap) with the CG swung out at 45 degrees and a weighthole just below my midline, at 6 3/4" from the pin. Since this was a 4.5-5" pin, I was able to get away with popping a weighthole that far away from the pin and still keeping it over the middle finger as I wanted.
So far i've only thrown this one for about 10 games, and i've kept it polished, but it definitely gives me a nice amount of separation from the first Rapid. This one is much cleaner through the heads (due to the polished finish, the longer pin-to-pap, and the pin up vs. pin down), and still gives that very similar hard arc on the backend.
I've found that I can circle the lane with both Rapids, as well as play a little straighter (only on heavier volumes with the pin-down sanded Rapid though) up the boards, fortunately for me the core/coverstock combo allows me to have two very versatile, yet strong balls that can read in the mids and not over-react on the backend.
Also, this ball seems very responsive to hand position changes, if I change to a hand position to promote more side roll, the ball gets further downlane and conserves more energy for the backend. If I go stronger with my hand position, the ball rolls up a little quicker but still makes it through the pins without quitting.
