The Crossbreed Supertuck is the most comfortable rig I've got for IWB. However, I find that it rides pretty high making it difficult to draw and also prints badly. So I only use it when I'm wearing a baggy shirt.
Usually, it's a one clip holster. Conceals and draws well. Stays in place.
I am sure you are aware of the fact that the clips may be adjusted on the Supertuck and the holster can re lowered or canted to your desire.
