Interesting thing about the tac vest (and the 82 pattern webbing back then) is that after I've stuffed it with things like cam paint, bug juice, raingear, etc, I've now got no room to actually put a C9 box, frag grenades or smoke grenades (as if I get any of these on a regular basis) into it. On the other hand, if I'm just going to be a rifleman, this vest sure is great for bearing the weight since my shoulders don't hurt anymore running around with the full load as I did with the 82 pattern. Some other guy I know just used the "man purse" configuration of the buttpack for most of his other stuff because we don't have the smallpacks yet.
One minor and inconsequential complaint I have is that they could've made a small version since quite a lot of us tighten the back straps all almost the way, even with a jacket on. A small version where the straps are maxed out only with all your winter kit on would've been great, but hey, this is still better than the 82 pat.
