I do like the wave feature, however with practice, drawing a folder without it isn't hard at all. Just takes time for some. Overall for a large EDC folder, I really can't think of much better than the Skirmish at this point. I have Skirmishes in both the standard verison and the black version. I've no real interest in the gold-laden variations (way too flashy for me). The black version has grey handle scales with silver dots, and overall I like this variation the best. As for easy opening, my Skirmishes actually feel much smoother than my Emerson's. As they all tend to get smoother with use, I feel this is a good thing. My original Skirmish, which has seen the most use opens extremely smooth and is great IMO. Same goes for some of my older Emersons as well, but in a direct comparison, the Skirmish, to me, still feels a tad slicker. The CQC-8 is a very nice piece as well, and is now available with the Wave. If I had to choose between the C8 and the Skirmish, I'd still go with the Skirmish mainly on locking system and overall feel.
Back when I had the Gryphon M10 I ditched the tec-lok and got some IWB belt-loops from blade tech and setup the piece for IWB carry and found it worked quite well and was low-profile if worn in the right place. The sharkskin belt rocks. I have the same thing with about 2yrs of use on it. Can't complain one bit. I also rotate between a Wilderness tactical belt, and a few Galco gunbelts as well, all pending on what my mode of dress is on the occasion.
Back to the folders, both Benchmade and Emerson have awesome warranties, so if something arises, my experience shows both will take very good care of your concerns. Also on the Skirmish, you can boil the handle slabs in a mixture of water and Oxyclean, which will form titanium oxide on the scales making them a darker color. Some people have done this on original Skirmishes that have the blue\yellow\etc dots, in turn making the whole handles much darker in some instances.
