Butterfly stops making aibiss, so I wouldn't recommend looking into that. If it is indeed the best rubber for you, then good luck buying all the remaining stock (probably quite a lot, it is not a popular rubber).
Aibiss is a sticky anti. BTY has discontinued it very quickly it's so bad.
The sponge is so hard it makes H3 blush. They say it's a spring sponge but they forgot to add the springs.
