I'd suggest for a gish that you go Anima Mage, or any other way to persist things for free. Wizard2(precocious apprentice), Binder1(Improved Binding), Anima Mage until you get persistent wraithstrike, Abjurant Champion/Spellsword/Eldritch Knight and stuff. Be a Neraph, that negates the need of taking a fighter level to become an Eldritch Knight, since you get proficiencies with simple and martial weapons for free, as well as Neraph Charge. What you do:
1: Persist wraithstrike.
2: Charge with neraph charge.
If you want, toss in a level of Lion Totem Whirling blah to get a huge number of flat footed touch power attacks.
Overall, it takes 5 anima mage levels to get vestige metamagic, bumping your binder level to 6, which, among other things, allows you to bind Tenebrous for infinite Turn undead attempts, deeper darkness at will, the ability to see in magic darkness, and my personal favorite: Flicker. This allows you to, for 6 rounds, teleport as an immediate action.
Now, with this build, you should have a BAB of 16 and a CL of at least 17. You get persistent wraithstrike goodness, which, combined with neraph charge, allows you to hit an enemy's Flat Footed Touch AC with a pounce, which kind of negates the need for shock trooper, really. This allows you to be a defensive monster, because you can teleport away from full attacks (Flicker says that it grants 50% miss chance if you use it in this way, so I'm going to go with that on abrupt jaunt) most times that it would be relevant, be in an area of darkness that nobody but you can see through, and stack miss chances out the butt, which leads me to my next point:
To take more Anima Mage levels or not?
If you go anima mage all the way, you'll have a BAB of +6 3/4 from your wizard and binder levels. However, you can then bind Chupoclops, meaning you don't need a barbarian level. That right there's a free caster level. Treasure it. You can pick up 7 more BAB from your remaining levels, but that loses you a fourth attack. It's up to you, whether you want more offense or more defense. Depending on what spells you persist, the extra anima mage is probably better for both offense and defense, but the first one is stronger in straight up combat.
With the anima mage, you can persist my favorite 3 persistable spells: Greater Mirror Image, Greater Blink, and Wraithstrike, which will give you touch attacks all day, and a 95% miss chance (approx.) on all attacks that cannot see through illusions, see invisible creatures, and strike the ethereal plane.
I'm sure that there's some better way of getting free persist, but I like this way. It's fun. A bit MAD, you need strength, Con(of course), Int, Dex and a little Cha. Your spells can help with any and all of that, though. Say hello to my little friend, Bite of the Werebear. Persist that bad boy for +16 strength, +7 natural armor, + a lot of con, and + some dex. And if you find yourself in a pickle, you can use limited wish to persist any spell that a limited wish could replicate, such as divine power. That's an awesome trick, you can keep it.
Have fun! Happy persisting.
