Despite the fact that it is pretty much the same as the coal/purple crush tank, I just really like the combo of coal and faded zap together. I've always been a fan of gray and yellow combinations. Faded zap is more like a greenish yellow, and I am not a huge fan of it by itself. But as an accent color on this tank, I just think it looks really sharp. I still love the coal/purple crush combo as well, so I don't mind have two. If somebody held a gun to my head and asked me to pick one favorite though, I would pick the coal/faded zap. Good thing I don't have to make these hard decisions in life. Lol. I'm so glad that I was finally able to get this tank after 2 years of dreaming about it!
I definitely think that the newer batch of Hot Class tanks were updated with slight improvements. I've noticed it on my lagoon Hot Class tank as well as the new coal/faded zap, that the straps tend to crease and bend in half in certain areas. It's almost like half of the strap decides to fold on top of the other half. This happens more as the workout progresses. But this is not an issue with the new purple crush one. You can even feel the difference by just touching the straps - the purple crush straps are stiffer, but the look identical. I know it's not a big deal, but it's just something that I've noticed and then I sort of feel the need to smooth out the straps.
With that said, I still wouldn't hesitate if I had a chance to get the Hot Class tank in bold blue though. Still dreaming about that one too. See, I am a hoarder!
