Rogue Gearing Question

[Valdain]

For a Rogue that isn't super twinked (example, most expensive items on my toon are 2k at max), and considering that I'm not going to be soloing as a result, is it still useful to have 2 55/5 rings, or should I use those 5 STR/DEX rings?

I'm level 35 with 219 STR with the 55/5s. Would 10 more Strength make much of a difference at my level? Between Druid and Shaman buffs at or near mine, I hit anywhere from 230-245. I'm weighing the STR compared to being able to take a hit or two should I pull aggro / Evade fails for whatever reason.

Also, there's no benefit to STR beyond cap, correct?

Thanks!
