I find myself regularly going back to my 4x4 to practice algorithms (especially the even order parity algorithms) and I'm rather fed up with my cube! It's a Rubik brand 4x4 and it catches and clicks and partially pops and even after a decent lube it's stiff as hell!
I have absolutely no intention of ever speed cubing and all the discussions on the net of "what 4x4" are aimed at teenage speedcubers! Their discussions seem to go back and forth and get rather firey! Hopefully that wont happen here!
So can anyone advice me which brand 4x4 I should try to get a nice smooth and non-catchy/popping experience. Some of these cubes go up to $45! Surely it's not necessary to spend that much to get a nice cube?
Thanks for the advice!
