I will offer this bit of analysis. You are used to carrying a large knife, but it isnt terribly heavy given its size and you carry it with a clip. Unless you are planning on a belt sheath, the Buck 110 and 112 and a lot of the knives cited here (Schrade LB7 and Queen Mountain Man for example), are really too big and heavy to carry in a pocket. If you want something pocketable, I think the GECs are probably the upper limit, and you will probably want either one of the shorter bladed, gent type knives or a Case Copperlock.
I prefer pocket carry to clip carry or sheath carry in nearly all cases. I don't like junk on my belt (personal thing) and I hate reaching past a clipped knife. Would rather dig change out from around the knife.
I've found that length and weight are not the determining factors for me. The profile of the knife in it's cross section and it's bolsters are, for me, more important.
I wear baggy carpenter style jeans nearly every day. I find that when a knife moves somewhat freely in the pocket, it is less noticeable to me, even if it is heavy. The first knife that taught me this was the Buck 500, which is the same length (and roughly the same weight) as the 112. But the 500 is very flat and the bolsters are very round and I found it to be very easy to pocket carry. So easy that it pocket ejected and is now gone.
The next knife to confirm this was the 500's even larger replacement, a Schrade 51 OT Big Timer (aka the Pocket Buster). It's every bit as big and heavy as Buck 110 but pocket carries well for me.
I find wide square cross-section profile knives to be buggy in the pocket, even if light. Obviously the 110 and 112 are buggy but the Ecolite 112 that I had for a while showed me that it is the square cross section, not the weight, that is bothersome to me. I notice it when I sit or go up stairs. I don't notice the round cross section of the Opinels compared to the Ecolite. For me, it is definitely the square and wide cross section that doesn't work.
In terms of bolsters, the Opinels have shown me that I only need one end to be slippery. I carry the Opinels with the lock ring down in the bottom of the pocket. I round off the end of my Opinels and this helps them slide a bit at the top/middle of the pocket as I'm active. I don't notice the #9 and only with the #10 do I start to notice it. Actually, I notice a rounded off 9 less than a stock 8, due to how the top end of the handle slides in the pocket better.
Last comment... With closer fitting slacks I do prefer shorter and flatter knives. My 5 OT is the nicest carrying knife of all. Better even than a smaller Peanut since it's flatter.
The Opinels....
