Engine builders please help, need advice on valve springs

I'm looking for some advice and guidance. Have a 9,600 mile 2010 SS LS3 6spd manual that I will be installing a GM LS9 cam in. I know the stock LS3 springs will work fine BUT I'm looking to make the valve train as bullet proof as possible. Car will not see drag strip use BUT will see a road course once or twice a year. At 54 I am no longer a die hard racer, just having occasional fun weekend with the car. Car is an occasional driver on the street as I work from home. I think it goes to the grocery store more than anywhere else . Here is what parts I have so far :

GM LS9 cam - to be installed
3 bolt cam gear and LS2 damper - to be installed
IWIS C5 R heavy duty timing chain - to be installed
Melling 10296 oil pump - to be installed
Comp Cams rocker trunion upgrade kit - to be installed

Springs - see paragraph below

CAI cold air kit - already installed
VMAX CNC ported throttle body - already installed
Elite oil catch can - already installed
ARH 1 7/8" LT's with HF cats - already installed
Stock cat back pipes - already installed
GMPP "touring mufflers" - already installed
AAM 3.70 gears - already installed

I have a set of the newer Comp Cams 26918 springs I had planned to use along with the stock retainers and locks but I am now wondering if they will be too much spring. Would I be better off with GM LS9 springs or something else ?? If the Comp Cam springs are OK, should I get the Comp Cam forged retainers and locks or will the stock retainers and locks be fine ??

I have 1 vote so far for the 26918 springs with stock retainers and locks. I thought I had this well planned out and was ready to go but now I have second thoughts about the springs. Any suggestions will be greatly appreciated.
