What springs are you using with TRex? I think I've decided on the Trex, this will be in an Ls1/t56 Rx7 with 3.90's so I dont think I need any extra low end torque due to the lighter weight of the car.
On there site the cam/spring combo comes with dual crane springs with the option to upgrade to Comp Cams 63-26921-KIT Spring kit for $245.
I talked to their tech department and he said the crane springs should last one season and then be checked. The comp cams should last 2 to 3.
What are you guys running and how long have you been running them?

The 921s are a great spring and could possibly be extra insurance, but I don't think they are a necessity with the TRex lobes. To sum up what I was saying, the 832s would work well and would suffice, but if you want to spend a little extra the 921s would be good insurance if nothing else. I wouldn't call it wasting money.

I have run the patriot golds, comp 921's and AFR 8019's, golds in my were better then the comp 921's ( 921's wore out pretty fast with g5x3 cam induced valve float around 6400 rpm) , but the AFR 8019's are a badass spring, i ran them with 257-266 cam with .646 lift for 5000 miles, beat the hell out of it everytime i drove it, and when i pulled the springs out of the car, the seat and open pressure were still within a few lbs of each other. i say look into those 8019 springs. same dimensions as the patriot golds, and 921's
