The Alchemist's flask at 80 only provides 32 stats (no matter what skill in alchemy), so you'll be using cata flasks no matter what. As mentioned, The 359 trinket is better than all of the available options for non-caster classes. It also gives you access to the best stamina trinket for the level.
Literally all you need.
