Definitely. I think it wouldn't be a bad idea to go ahead and 4cap str at some point, maybe after 1capping vision. That leaves you a little more wiggle room against those super-str NTs.
edit: to me, an LG would have only 2capped strength at first, so as to have more agility short-term which meant more agility gain long-term. Also that would have helped with vision, for those pesky blitzers.
