What's a good, solid-feeling 3x3 that isn't too fast? My favorites cubes so far are the MoYu Weilong and the DaYan ZhanChi but I have a hard time maintaining control (for example: when doing d turns, the D layer spins out of alignment). The MoYu DianMa gets close because it has a solid feel with good resistance and corner cutting but the narrow middle layer is a deal breaker. I've also tried the DaYan PanShi, FangShi ShaunReng and Gans III v II and I really dislike the super-light, hollow feel of those cubes.
