Thinking of taking the surface down on my 2D from 4000 to 2000. I'd like to use it for when my home center decides to put more oil down. I save my Invasion for tournaments. Has anyone tried their 2D at 2000? My Mutant Cell Pearl, Tropical Heat, Wild Thing, Pure Swing, Backlash, etc wouldn't be good for that "med/hvy" spot and have found that in my Friday morning league, none of them are strong enough.
