I'm with Shelley on this one, it depends on who's bowling on the pair with you. If you have the team that throws plastic or urethane bowling equipment, then the lanes seem to tighten due to the carrydown, but most nights you have the guys that throw the Total NVs or No Mercys on a condition where there's not a lot of oil in the heads, and you have a recipe for a long night especially if you don't utilize speed and loft adjustments. Last season, I couldn't adjust to it correctly because I refused to utilize speed and loft adjustments to compensate for it, I just tried to change angles, and at this center, it usually doesn't work unless you're the only one playing left. I even had a guy last year that sanded an Infinite One, needless to say, the heads were gone by the 5th frame of the first game. Then other nights, I could utilize angle adjustments effectively and bowled well as a result.
