A slow drop in spin and speed as it ages, but the topsheet still looks brand new, and the rubber itself is definitely still good enough to play with, even in tournaments. I'd say right now the spin/speed of the rubber is somewhere around 80%-85% of brand new. Not too bad for a 17$ rubber. Only reason I am gluing a new one is the topsheet separating.How would you describe how it changed in its characteristics during those 3 months? Was there are any noticeable drop off in grip or speed? Did it affect concistency at all?
