I am not too worried about them gestalting the weak combinations. So really I need to apply a high enough LA to make the more powerful combinations balanced with a "single" classed character.
I feel pretty secure with a +3 LA.
Can anyone make a strong argument for +2 or +4?
Let's compare a rogue3/wizard5/arcane trickster 6 to a gestalt rogue/wizard 11/11.
Arcane Trickster:
6 + 2d6 + 11d4 + 14x con (say 16 w/ magic) hitpoints = 83 hitponts on average
Fort Save: +4 base
Reflex Save: +9 base
Will Save: +10 base
BAB = +9
Caster level = 11, 6th level spells
Skill points (assuming 16 int) = 66 + 25 + 42 = 133 skill points
skill rank cap = 17
6d6 sneak attack
Ranged Legerdemain 2/day
Impromptu Sneak Attack 1/day
Trap Sense +1
Scribe Scroll
Familiar - 5th levels of progression
Gestalt:
6 + 10d6 + 11x con hitpoints = 74 hitpoints on average
Fort Save: +3 base
Reflex Save: +7 base
Will Save: +7 base
BAB = +8
Caster level = 11, 6th level spells
Skill points = 121 skill points
skill rank cap = 14
6d6 sneak attack
Uncanny Dodge
Improved Uncanny Dodge
Trap Sense +3
Rogue Special Ability
Scribe Scroll
Familiar - 11 levels of progression
2 Wizard bonus feats
The Arcane Trickster seems better off, but not by a whole lot. +2 LA might be better. This isn't the most powerful gestalt combo available, but it's a fairly obvious one to take if someone wants to do a spellcasting rogue and by no means underpowered.
