I was looking in a butterfly sales book and there was a rubber matrix graph in there.
But on that rubber chart it stated that Tenergy05,05FX,05 Hard are all the same speed and spin.
Same for Tenergy 80 and 80fx etc.
How can this be the Tenergy 05 has 3 different hardness's and according to butterfly they are all equal?
Butterly is usually very good on the marketing side and on explaining how their rubbers compare.
So I don't really get why they say this, in General harder rubbers should be faster and produce a bit more spin isn't it?
