This H3 topic is became like very similar to a topic of T05 alternative, so much comments and threads about it, i feel like there will never be any clear correct answer to that. I once bought a used H3 rubber with orange sponge but i never know which version it was, it was used and already cut for a blade bigger than my blade head, so it was fine to glue it to my blade and cut again, it was on Butterfly Primorac EX blade, it was a super nicer rubber for me in FH, it was like a perfect match, i wasn't sure how it will be but wanted a rubber as a replacement to my dead rubber, it suits me better than T05 actually, Rakza 7 soft on BH, but that racket was stolen from me, so i bought another H3 commercial normal rubber for my Hao 3 blade, it wasn't same, not bad but wasn't so sticky really, i felt like it was faster and less tacky than the previous one, so not sure if the old one was boosted or oil'd or different version i don't know.
