LS3, Daily driver to the tune of about 40k/yr. Procharged pushing 12-14 PSI. Figured upgrade trunnions/rockers while my engine is apart and knowing I'll have to measure pushrods. Cam is GPI low lift vvt "stage 2" truck cam- 216/230 and about .55X lift if I'm remembering specs correct. I think I set the tune rpm limit to 6200. Lifters are Johnson link bars. PAC springs. Factory rockers/trunnions have about 120k.
Looking at:
ws6store rockers
Summit pro ls rockers
btr LS3 shaft kit
CHE bushings with OE rockers
Any high milers on any of these options to say yay or nay? Most of what I've searched has yielded 30k experience at most. I don't want to be replacing trunnions every 18 months...
On my LS7 steel TSP Roller Tip Rockers it was a direct bolt on the preload was the same with the OEM rocker. With the roller tip you need to add a little more spring pressure for the extra weight. From what I could see it was like another 30 pounds of open spring pressure.

I drive my fast junk everyday too. I had the Summit bronze trunnion go bad on me. I would do the WS6 store or the BTR kit.
I have the BTR V2 trunnion upgrade on my LS7 rockers. Put about 20,000 miles on them with no problems. If you go with the BTR setup, make sure you go with the later V2 setup. BTR had some issues with the earlier V1 setup. There may be a few of those earlier BTR setups still out there for sale. Avoid those.......
TSP direct bolt on, no new pushrods needed (same preload and good wear pattern). The shaft system is nice I have Brodix heads which have a more robust pedestal which is why the shaft system is nice for OEM heads.
I run a cathedral port top end on my ls3 block and use the ws6store max effort rockers on it. Been fine for 5 years now. Procharger at 20 psi peak boost, .621 lift, and shifting at 7200 rpm. Lifters are just ls7, springs are btr .660, and pushrods are summit HDR 11/32 .120 wall.
