That's a lot of tradeoffs to consider. Everybody has their preferences, but defenders like Hashimoto, Filus, and Sato all use hard rubbers on defensive blades, so the blade isn't really the problem. They are professionals, though, to be fair.
If G-1 Max was too mushy and slow, and a harder sponge is too hard for you to engage, it sounds like you need something with a bit more built-in catapult...but you don't like the bouncy rubbers. I'm not sure where that leaves you. I agree with the others that Mantra Pro is a possible alternative—M is the same sponge hardness as G-1, H would be harder—but I personally didn't like the flat arc, even though I liked the rebound. Still, it's relatively inexpensive on AliExpress so probably worth a try.
I would also throw Xiom Omega V Tour into the mix. It's a Tensor, but an older one, and one that I think is underrated in the amateur space. Despite being formerly considered a top-of-the-line pro rubber I've never had issues controlling it, even on fast blades. It's plenty fast, but predictable. It's honestly my favorite FH rubber, and the only reason I try other things is that I'm afraid Xiom will discontinue it...
