Finally tested the LAC on two viscaroids: DHS PG6X (harder) and FZD ALC (softer):
1) Short game - good. The rubber is more 'linear' than H3 Neo, it's a bit less dead on touches, but it's fine because any extra effort logically transfers into speed increasement (which isn't high), so it's easy to control the ball.
2) Slow (spinny) topspins - bad. When I executed such topspins using my wrist, the spin was mediocre, but when I engaged the torso, the spin was good. So yeah, opening with slow wrist-loops is bad--the person either counters easily or blocks to an uncomfortable position.
3) Powerful topspins - good. The arc is below average, so the ball dives pretty well. However, the ball doesn't accelerate off the table like it does with H3 Neo (pretty much no other rubber has this effect, IMO), so it was easier for opponents to return.
4) Serve - good. Once again, it's much worse than H3 Neo (reverse pendulum with H3 Neo is sometimes half of my points won) but still pretty good when compared with other hybrids or ESN rubbers.
5) Flat hit - good. Better than Jupiter 3, Battle 2 Gold, and way better than H3 Neo which is the worst in that department.
6) Blocks - very good. I was surprised how well LAC soaks the spin, blocking was very effortless like with European hybrids.
7) Countertopspin - excellent. In fact, I didn't expect the rubber to perform this well when countering. It soaks the enemy spin and creates its own spin when you engage the torso (which is inevitable during countering). And you don't have to go through the ball as much as you have to do with H3 Neo.
Conclusion: I have yet again tried to find an H3 Neo replacement, because H3 Neo requires regular boosting. So I tried LAC without a booster, and it was a worse rubber, all things considered. I am sure LAC would play better after a couple of layers of boosting, but the whole point of trying this rubber was getting rid of boosting forever.
