I too missed Touch Classic when it was first replaced by BT7. But then another TT member pointed out that some players may prefer stiffer gut (eg Pacific). So I tried it again and the new formulation does seem to work better in a hybrid for spin potential and control.
I've tried this VS versus Wilson in a few head to head tests with different crosses and 4G seems to result in the highest contrast between the two.
There's another thread in this section in which the OP says he's done trying different string, at least for a while. After this latest series of tests this fall I'm going to join him. Nothing else I've tested provides Touch/4G's unique combination of control, comfort, durability, and spin potential. Other setups might provide a little more comfort or a little more spin but none provide such a balanced package.
