Just picked up my Aerogel 100 with Bab Nat VS 17, its is stiff. Did not play with it yet just hit against the living room couch ( I won by the way). Feels stiffer than NXT, NXT Tour same tension of 52pds.
Crap, not liking it so far hopefully on the court I can feel the stiffness give me extra feel and control.
