My Mutant Cell is going to get very, very little use on a house shot. I bought it specifically for controlled power on fresh, flatter patterns when I need to go up the boards, but create a little area. Think USBC Open, fresh Scorpion, fresh Shark, etc. I don't remember the exact MB position (it's between 5" and 6"), but the pin is 4.25" from PAP with roughly a 2.5" pin buffer. With the box surface, I had to play around 17 at the arrows to 13 at the break point on a fresh house shot. Any miss right meant instant rollout and either a flat 10 or a washout, and any miss left just hooked a bunch. Since I won't be seeing long, heavy, flat conditions for at least another month, I took it to 4000 and polished the hell out of it just so I could use it a little and get used to its tendancies. I was able to use it for about 2/3rds of the first game before it started burning up and hitting flat. However, whenever I find lots of oil, this ball is a rolly monster. It just does NOT like to be thrown away from the headpin much because of the drill I've put on it. That was by my design though -- if I need to give away the headpin more, that's when I throw my original Cell which I drilled for that exact condition.
