I think you'll be alright... the SL's run slightly bigger than the ST's and are a roomier cut all around. As mentioned previously, make sure you can button the jeans up - you can expect 0.5-1" of stretch over the first few weeks.
phx: Try the 32's first... you should be able to button them up when you receive them - if you can't, exchange for the 33's. And as for the leg opening getting bigger, you'll see very little change in the leg opening if you're only taking 2.5" off.
@guyute: They look good. Whenever you decide to wash them, you'll get some really interesting hues of blue come out.
@nineohtoo: These aren't the best photos, but you can see here that the grey denim will age, it's just a bit more stubborn than indigo denim in terms of losing color:

Flat Head jeans use a gripper zipper - the next time you zip your jeans up, put one finger into your waistband and hold the zipper from the inside, pushing out. Then with your other hand, push the zipper...
The photos on Revolve are misleading; the model probably could have sized down one, which would totally change the look of the fit. If you're looking for a fit similar to an APC NS with a slightly wider lower leg, go with the SL-100x in a size up from your APC's. They'll still be tight in the waist but should accomplish what you want in regards to the rest of the fit. As kixslf mentioned, you could also try the ST-100x but make sure to size up one (two from your APC size)...
