I've only been cubing a couple of months and have a YS3M Ball core and a Flagship Tornado V3. This V4 feels like a faster, more stable version of the V3. I like the fact that it has a similar feel to the V3 but just seems like a higher quality cube with some of the YS3M's stability. I use Dash and Blitz lubes in all 3 cubes so may need to get a thicker combo to slow things down when I get more experienced bit for now, I'm just really enjoying the fast, effortless turning of this cube. It's definitely my new main, and it's just so easy to adjust and set up.
