Knowing that they are very similiar its just whether you want a 35% or 40%. Most of us would go with a 3.0M or 40% Extra because it flys bigger. More stable in manuevers. Both are great flying planes, its just a toss up of what you want.
www.cafreestyle.com has some pictures of another friend who has the 3.0M Fiberclassics Jason Shulman Peel Back Scheme with a DA 150. Its an absolute monster and flys wonderful. Between these 2 planes its the pilot that will make the difference.
