Thanks, namor! Yes, the secret is that my wife is vegetarian (and I have been at various times and am mostly now except for a bit at social occasions), and that we like to run (albeit, not huge miles).
I'm 6'2", 155lbs, so the 30x34 fit me slim without being tight at all. I have some of the Orchard St chinos in 31x34 that are huge on me, mostly because of stretching. Sadly, RRL doesn't seem to make 30x34 anymore, so I mostly have to hope for pants in 30W running long.
