Justin

I think I've decided to get a silver recon and a qz2 to go along with my gt1. With my gt1 at 2000 I believe I will have what I need for the fresh then qz2 then recon. Suggestions on recon drilling. I'd say 50x4.5x30 would be good or possibly a 5 inch pin to pap to reduce flare a little bit??

You have a smooth benchmark layout covered with the GT1. The QZ2 will provide a stronger backend and the RX1 will provide a less hooking option.

QZ2:
55x35@4.5" If you want it smoother place a P3 hole. If you want it to go a touch longer place a P1 hole. Box surface should be acceptable.

RX1:
For a smoother reaction, 60x55@4.75". Place a P3 to smooth it, a P1 to tame the fronts.

For a stronger finish, 50x35@5". Place a P1 hole to tame it if needed.

What about a 65x5x35 to get a little more length but still a quicker response to friction?

Are you referring to the QZ2 or RX1? For the QZ2 you could use a 5" pin, but I was trying to get your reactions spaced out a little more for 3 different looks.


Remember the drilling angle doesn't mean anything in symmetrical balls other than loading weight to prepare for a hole.

The pin distance and VAL angle are primary factors, the weight hole location is secondary. After drilling the placement of the hole will increase or decrease the diff to modify the reaction. Its safer to err weaker, as with a stronger hole you can add a bit more diff than you can take away.

I was referring to the recon. I forgot about you stating that fact in another post about symmetric cores. The core and cover combos alone will provide me with a different shape regardless of the drilling correct. I'm comfortable with the 55x4.5x35 for the qz2 but the recon is what concerns me. I have a Roto grenade that's drilled 50x4x40 I believe with a p3 hole and its real early and smooth as expected from urethane but it don't have the finish you see out of a reactive cover which is why I'm gonna go with the recon so I don't want it to be so smooth it overlaps the grenade that why I'm thinking about a 5 inch pin to lengthen it and have plenty of recovery. That's why I was thinking a 65x5x35 and adjust the shape and time on the lane with balance hole placement.

BE careful with long pin distances and small VAL angles, that will promote forward roll off the spot.

You can use a 60x35@5". If it isn't strong enough take the fingers a little deeper and place a P3 hole to crank up the diff a bit.

Well That's not what I not! Like I said I don't want the ball to be too smooth. I want the ball to get decent length but not blow past the break point and have a decent finish. Yes I know the balls designed for shorter and lighter patterns but I have bad luck with balls designed for such conditions, as in skidding too far then taking off leaving washouts or entering the pocket at unforgiving angles leaving ugly splits and stupid single pin leaves. I want the ball to more or less skid roll then hook if you understand what I'm saying.

Take a look at these, see if either is what you are looking for:

Pin down 60x70@4.25" P3 Hole:

Pin up, 60x35@4.25" No Hole:

I like that looks of both of them but the pin up ball is more what I'm looking for. A faster response not to far down the lane, not as early and smooth as pin down ball. I'm gonna pm you about some pro shop questions?
