I have the same experience comparing Xiom Omega 5 Asia and O7A and have described it. So I assume the new T05H has a softer rubber topsheet. Such a combination may give longer life to the harder sponge, but I'm still reserved about the lifspan of the softer topsheet. We'll see. Anyway I welcome this step of BTY.
I want to add that these kind of rubbers with harder sponge and softer topsheet are really very dangerous. I already had a lot of sessions testing O5A against O7A on same blades playing with a partner who is used to them too, and 07A is always the winner, never mind in whose hands. If its the same with T05 vs T05H it would be very interesting to see the results.
