If this is the case then I'd hazard that you're tying the bowline incorrectly. There should be no binding with a bowline as it's one of the easiest and strongest loop knots which comes apart rather more easily than an 8 on a bight or even a butterfly.
For the OP: I'd say go online and learn as many knots as possible. I have actually used a sheep shank to shorten a sled line while snowshoeing once. You never know when that one obscure knot will come in handy. Having said that, I'll add my other 2 cents:
Clove hitch AND the constrictor knot. Clove hitch can loosen but the constrictor will stay tighter under load cycles.
Anchor-less is great for quick tie-offs and for fast z-drag anchoring.
Trucker's hitch can be done with an overhand but using an 8 (quick twisting does the trick) is more appropriate (imo). Once you learn it, you'll love the speed.
And two that don't get much notice but are great for setting up tarps are the buntline and tauntline hitches. Buntline for attaching to a corner of a tarp w/o a grommet and the tauntline to create tension.
