I am actually fully done with the v2um. I wanted a really light magnet feeling because I use roux and the other magnetic cubes had been a little too strong for me so I used 4x2 n48 in the corners and 4x1 n48 in the edges. The feeling is really subtle, and I really like the lightweight feel of the cube (i didn't remove any plastic, just the screws) my only problem is that I got tiny drops of superglue on some of the pieces which gives it a tad scrathy feeling. Hopefully with lubing and breaking in that feel will go away. I also kept the gans core installed. Really likeing this cube! Espically for oh!
