Hi, thanks for reading this. I'm trying to get sub twenty and my cross + F2L + OLL is usually done in 21 - 22 seconds my PLL, or execution of algorithms is really slow and slippery. The PLL alone extends my time to about 28 - 30 seconds, and that's what I average. I've noticed recently that my fingertricks and grip of the cube seem to be the problem. My hands are always slipping off the cube, lubed or unlubed, and I've never been able to do U2 with index-middle, as I just can't stretch my middle finger. Plus, I've noticed that while most cubers fully bring their index fingers forward for U2, the do it the whole way and usually make a "hook" shape with their index finger. My finger, on the other hand, always stays on the horizontal plane and I only do a forward flick without really bending it. Other than that, my fingers just keep losing grip of the cube. It's frustrating, I wonder if you guys can help. P.S, are my pinkie fingers supposed to stay on the cube, too? I might upload a vide of a solve if I get the chance.
