I ended up with the blade-tech, ordered from CZ Custom. It seems to work pretty well and the "sting ray attachment" is a bit wider and does give it a lot of support. It is, of course, Kydex so I think I will do a bit of sanding along the top edges. Have to watch to see if it causes finish problems. BTW, I ordered online, it shipped the same afternoon and I had it priority mail on the fourth day. Excellent service from CZCustom!!
