3.73 with 700R4 or 3.07 with TH350?

I've been debating this since I got the truck. On the one hand, I like the thought of a 700R4 and 3:73, truck would be great off the line and still have decent revs on the freeway. But, the setup for a TH350 is much simpler, cheaper, and no mods required. In order to make the 700R4 work right I have to get the TV cable and the lockup solenoid, which adds another couple hundred to an already more expensive transmission.

So what do you guys think? Right now I have a 3.73 posi in the truck, and I just picked up all the brake parts for it. I'd like to commit to the gear before I start installing the brake parts obviously... so wanted to see what you guys think. Would the truck bog off the line and make towing a strain on the trans? I'm trying to keep the costs down since I have a limited budget so that I can actually make it to Power Tour.

I'd obviously have to sell the 3.73 Posi to get the 3.07, but I'm figuring the 3.73 is worth more than the 3.07. Plus TH350's are a dime a dozen.
