Because of the whole Cole abuse thing, I still feel weird about Zero, despite some skaters I like on (or formerly on) the brand. But, I have a very similar setup to you, just with a different graphic (the blood and 3 skulls one). So for me, your setup is sick. I gotta say I like the Zero 7.75 decks a lot. I'm not sure if I'm trippin, but the shape feels better than Toy Machine and my local shop decks around here. The 7.75 selection where I am is literally just Toy Machine, Zero, local shop deck, and ocassionally I'll see a Polar deck floating around on a shop's site.
I skated the blood and 3 skulls deck ('bloody nose' as we called it) in a 7.75 and I liked the shape as well. I too have reservations about supporting zero for the same reasons you mentioned, so I've moved on to palace, as I like that brand quite a bit more - Especially considering the other options we have as 7.5-7.75 enthusiasts... If I'm not mistaken, I think both zero 7.75s and Palace 7.75s are the same shape and mold. Both use BBS and have a 13.8 wheelbase.
Also just a personal preference - My Zero 7.75 didn't have any colored plys if I remember correctly. Maybe just the top, but the bottom ply was natural colored, which always looks cheap to me and gross once the graphic is skated off. Palace always has a number of colored plys, and always both the top and bottom - with a top graphic! You feel like your getting more bang for your buck. My current palace has 5 colored plys and a full graphic on the top ply.
Palace 7.75s are kind of hard to find however, as they haven't dropped any decks in that size in a few years it seems. You would have to find and old stock one via resale, or maybe through a UK skateshop website (They are much less common in the US). I found the one I'm currently skating on Depop of all places... brand new in shrink and slightly under retail.
I've also skated both toy machine and Polar 7.75s - Toy machine was awful for me as I didn't like the wood shop they used (maybe PS stix? it was superrrr flat and flexy and only had a colored top ply) and I'm just not into Toy machine. Polar was BBS I think and had quite steep concave and kicks (and colored plys lol), the only problem was that it had a wheelbase of 14.25, which is way too long for a 7.75. I don't think I hit the tail once on a kickflip the whole time I rode it. Very annoying, despite my hardflips being the best I've ever had them due to the steep concave.
Due to the palace shortage, my next deck will be a hookups 7.5. I actually think hookups has the best deck shapes on the market. Super tapered, pointed kicks which I love- 90s style. Plus I'm a sucker for 90s graphics, and they're silk screened <3
