The Double Clutch is AMF's latest release in their mid-price category, joining the Clutch Pearl and replacing the Clutch. This new release offers more traction in the oil than the Clutch ever thought of creating. This is due to the stronger F64 cover this ball uses compared to the F55 cover used on the Clutch. Not only is the cover stronger, so is the core. The lower RG, combined with the much higher intermediate differential, allows the Double Clutch to take charge of the midlane. These changes allow the Double Clutch to handle larger volumes of oil with ease. All three of our testers found this new piece to match up best with our long, heavy oil pattern. The2000 Abralon finish allowed all three to find the pocket with ease on this pattern. We had more miss room in the oil due to the extra traction. We could rely less on the back end of the lane to steer this one to the pocket. When the back ends tighten up on longer oil patterns, balls like the Double Clutch will still be able to find the hole due to their strength in the middle part of the lane. We found moderate success on our medium test pattern with the box finish. Those bowling exclusively on medium oil patterns might be able to get a game or so out of the Double Clutch, but will find taking this ball to 4000 Abralon a much better match. Raising the factory finish will also keep it from chewing up a medium volume pattern. We made our suggested surface adjustment and found we were able to move back right a little, leaving oil to move back into when this pattern started to break down. Those bowling on lighter oil patterns will need to keep it in the bag. Only those with a combination of low revs and high ball speed will have any kind of success on lighter oil patterns. Even then, they will still need to go with a 4000 Abralon finish. Oily sport patterns will offer the best overall reaction for the Double Clutch.
