I think it really depends on how many balls your going to have in your arsenal. In all reality you could probably grab one of each ball in the current line and have a solid arsenal.
Mo Rich equipment is very versatile because of the core being so strong and asymmetrical. You could get a lot of different looks from the same ball just from using different layouts and cover grits. I was told WRW used the ensane levrg exclusively in one of the tourney's last season. I guess he had 3 of them drilled different.
