Which Dyes to Use for Tyrr Titan?

Hello,

I reach level 88 and don't have any tattoos/dyes on my Tyrr Titan. I know that STR, DEX and CON is needed for fighter class, but in this case, I stuck to decide which of these characteristics to sacrifice. Think to gain STR and DEX, but to sacrifice CON two times, HP/CP will fall near to 80 level character. Also, do I need to use 3 dyes slot? Or in my case, 2 is pushing it?

Waiting for your advice, guys.

 

Full +15str,
If can afford str+cha.
I think u can buy quite cheap 3str+1luc.
DEX is never used on titan.
CON is used in some pvp/oly builds.
But most its str.
