Should I Upgrade My Torque Converter?

I am in the process of building up my Yukon Denali (LQ4 6.0L). It is my daily driver, and I want it to be farily quick on the streets with the occasional track outing (maybe once every 6 months or so). I have already picked out most of my mods, and here is a list of what I already have:
Outlaw Intake (installed)
Corsa exhaust (installed)
e-fan swap (installed)
Long 40K Tranny cooler (installed)
Radix M112 w/2.8 pulley (installing next weekend)
Cam Motion 205/212 548/540 114 cam (installing next weekend)
Comp Cams hardened pushrods (installing next weekend)
LS6 Springs (installing next weekend)
Wester's Tune (installed, but will get retuned after Radix & cam install)
Before I started any of this, I already had my 4L65E transmission rebuilt and reinforced because I wanted to have that done before adding any power to the truck since I've read that the tranny is one of the weak spots when going to forced induction. I had my builder upgraded things like the sunshell, clutch packs, bands, and servos, but when it came to the TC I just had him put in a new OEM one. Was that a mistake, or will I be okay with the stock TC since I'm not going to be taking to the track at all? And I don't plan on really doing any street racing either - just very "spirited" driving.![Grin](https://www.performancetrucks.net/forums/images/smilies/LS1Tech/gr_grin.gif)
So do you guys think I'm okay with the stock TC, or is it likely that I'll run into problems with my TC once I get my Radix and cam installed?

Will a higher stall T/C make any difference other than the ability to launch faster? Like I mentioned in my original post, I'm not going to be racing it at all to where I would ever have the need to brake-stall it to get a fast launch. So if I'm not going to be doing that, will a high-stall T/C even be beneficial at all? I can understand maybe upgrading to a more durable unit than the OEM, but what will I gain by increasing the stall if I'm not going to be racing it at all? I'm just basically curious about the longevity of the stock T/C with the additional power; I'm not necessarily looking to get the fastest possible 1/4 mile time or anything like that.

how do stalls perform on the highway? Are you cruising rpms changed at all from what they would normally be at the same speeds? IN other words, if a truck normally locks at 2000rpm at 70, and you put in a 2600 stall, does the truck still cruise at 2000@70, or somewhat higher?
