Well, the 3:1 str hyb you're going for's a 90% phy bal naked hybrid....
naked | max blues | w/ prem + (w/ heuk pass)
HP: 22,112 | 27,757 | 28,340
MP: 8,972 | 14,618 | 15,201
phy bal: 90% | 101% | 103%
mag bal: 39% | 56% | 59%
Don't bother getting the nukes, since your magical balance'll be too low to deal any decent amount of damage with 'em.
I think 90 Heuk, 90 Fire'll be good.....the other 120 you could go w/ 90 light and 30 cold or vice-versa 90 cold, 30 light or 60/60
As for the skills part, since you're just a 90% str hybrid....I'll say you're similar to a pure str glaiver. Read the guide below, I'm sure it can help ya.
