The 9.5 will be looser than a 10.5. It will be looser up until the stall speed of the converter. The 10.5 will start pulling before it reaches the stall speed, where the 9.5 will start pulling later on. The 9.5 will usually net you better 60' times, where the 10.5 will have better manners.
Only you can decide what you would want, but if it were me, I'd go with a 9.5 triple disk. That will also give you room to grow. You know you'll never be 'done' with the truck.

The 9.5" is going to be what you want. The 10.5" isn't going to stall what you want it to with a 4.8L. If you order it to be a 3200 it'll stall at around 2700 and they'll just tell you that the 10.5" can't be stalled any higher. For a naturally asperated setup (especially with small cubes) you need to go to the 9.5" to get any stall speed over 3,000. As for the clutch, unless you tow alot with it the lock up will be just fine. You won't be locking it in the quarter anyway and you don't make enough power to hurt it when it does lock.
I went with a PI 10.5 single at first. My little 5.3 with 5lbs. would only flash to 2000-2200. They said it was as loose as they could make it. I switched to their 9.5 triple set up for 3000. It would flash to 28-3000 depending on if my truck was warmed up. I could stand on it and make it brake stall well over 4k. (Don't recommend it though.) Drivability was not nearly as good but it sure was faster.

Thanks for all the posts/opinions, I will be ordering one next friday, and I am still undecided.... However I am leaning towards the TT3000, for simplistic sake... Good manners, may not be the best performance, but it is the middle ground I am looking for...

i've been wanting to take out my SS3600 and put in a TT3000 so i can haul my trailer and racecar. i was all set on buying one untill i came across a gp over on tbssowners. it's a worked over tb converter built by CircleD in Houston. the tbss guys love them and the lock-up is better than stock. i couldn't pass up the deal for 3 beans shipped.

I put 85k miles on my Yank TT3000 and never once had a problem.I locked it on nitrous making 550 at the wheels and it worked great everytime.
I had it cut open when Jason built my trans and everything was fine.I had the lockup clutch changed and it welded back together.

I just spoke to Yank and they recommended the SST3200, since I have a 4.8... He said that converter would stall to ~2900-3000... I mentioned the TT3000 and he said it would only stall to ~2400 behind my 4.8....
I also just spoke to PI and they recommended a 10.5 triple disk 2600... Kinda wierd thing is that he didn't even ask what size motor I had....

The one thing I found with P.I. is that their product is great, but customer service and recomendations aren't. The also rarely hit the stall speed that you ask for.
