you cannot find 5x rubik studio, just 4x. but I suspect that 4x studio is the same as 4x rubiks.com
now I have 5x rubiks.com 4x rubik studio, 4x mefferts, 5x mefferts. in general, mefferts are a lot easier to operate. Specially I found that 5x rubiks is hard to rotate the outer layers. in the other hand, mefferts works 100% from the first minute if lubed. With rubiks, you must wait until internal pieced are 'self-sanded' with the use. I have never timed myself with mefferts cubes so I cannot give you any point about that. I like more the size of the rubik cubes than meffert's... hope this helps! Alberto [Non-text portions of this message have been removed] ------------------------ Yahoo!
