So, there are probably a million threads on this already, that don't really answer my question, and frankly don't really wanna fish through them all.
So my question is, which injectors should I run?

Truck is a 1991.5 intercooled 5 speed.
My pump is tweaked ( fuel screw turned up 2.5 turns, star wheel bottomed,Denny T stage 2 pin and a 3200 gov spring.)
I plan on running an HE351CW and a powerstroke intercooler.

I use(d) the truck for daily driving to work and home which is about 1 hour and 15 minutes one way. When I tow its usually a bobcat with a brush mower and some misc attachments. Or a kubota tractor with mowing attachments and landscaping equipment. Occasionally I'll tow a car hauler full of misc building/maintenance tools.

So I need a good all round injector.
I had a few injectors in mind such as:
5x12's
5x14's
6x10's
6x11's
7x09's
Or finally 7x10's
What do ya'll think? Thanks!
