I can happily report that my first 2-hour session with Dignics80 on bh was better than I'd thought beforehand. I've tried T05 before and I didn't like it, too bouncy. I come from over 2 years of using H3 on bh and this session certainly makes me want more D80, so I'll be using it at our league matches on Tuesday. Only fools rush in, and myself.
Pros:
Linear, good controllable speed, great in blocking game, good touch in service receives, good spin but no spin monster. Gives me confidence to attack with more power since margin for error is bigger compared to H3. If the contact on H3 isn't almost perfect it's difficult to get top speed from it.
Cons: Very heavy! It made my setup jump up from 194 grams to 205 and that made me overshoot many shots mainly from my fh side since the heaviness added power to the stroke when using the same swing speed as before. Had to adjust a bit to that. Not as good as lifting backspin as H3, perhaps unused to the different way to contact the rubber with the ball so I will adjust to it. H3 has a nastier trajectory, it dips more after the bounce than D80 does which puts opponents into some trouble. H3's top speed and spin is better than D80 since H3 hardly ever bottoms out.
All in all, a great rubber that I will continue to use and take it from there.
