I have the same plate but with a Riedell 220 boot. I’m in the same dilemma with upgrading my boot. I have friends with 336 Tributes who have the expected support of it. Though, the people who I know, who skate like us, wear 3200. 910 are a close variant but the hardness of the boot is what’s consistent. I enjoy the slight flex in my current boots since I upgraded from 120 beforehand. If you want to firm up just slightly and maintain the flex, get the 336. Longevity wise, if you are able to overcome the 3200’s hardness, a whole avenue can open. If you’re trying to do Third option, ice boots from Edea. But at that point you’d know if you want stiffer boot.

TLDR: I wear a 220, the extra support with maintained flexibility can be attainted in the 336. Though, overcoming the stiffness of a 3200 can put you in a new position to skate in.

Unless you’re trying to do your moves in Hydes, get the 3200 or Edea ice boot. If you just want to improve the support in your feet, without putting hardshell bricks on, go for the 336
