@Regisiew: I really all comes down to personal preference between stickers or tiles. Some people don't like the feel of tiles, but I prefer them over stickers. Tiles do last longer than stickers though. I love the smooth tiles i got from cubesmith. (im sure if u do a search you will find any more info that you might want. I'm pretty sure there are a couple of threads on this.) As far as buying them: go to cubesmith.com they have the best stickers and the best tiles, so whichever you go with (if not both ) get them from cubesmith. It is the best place to get either, bar none.
Would lubrication help it with the whole locking up thing? Or would it make it worse?
@luke: It's hard to make accurate turns because the cube both slips out of line when I'm holding it normally and each side has a different amount friction. Do you know a way fix either of those things?
my question is, to claim a PB average 3 of 5 does it generally have to be just 5 solves or could you take a best rolling average of 5 from a bunch of solves?
I average 29-30 seconds, My current goal is 20. Can you tell me a breakdown of the solve for a 20 second solve? Cross= __ seconds F2L=__ seconds etc. Thanks.
