Cclin- that is a nice blade there!!
i have never used a true single bevel with ura, but i sharpen most of my gyutos with a 70/30. My last one from Luke Snyder is an 80/20 or even 90/10 very asymmetric. The knife is super sharp. and i quite like it. However i dont see how a true single bevel would help you. If your bevel is too wide on the front it will cause steering i would think.
