Hi Hap,
I have also done the hackle facing the front, and then wrapping back trick, and agree that it does work. However, I have not tried the wrap the stem, and then wrap the thorax over the stem trick, but it sounds better than what I have done to overcome the thick stem problem. Typically I have stripped off the barbs and tie just them in facing to the front, and then wrapping back with thread.
I have not tried the strip off the barbs trick, but is sounds feasible, and I can certainly see how it does conserve hackle.
Regards,
Gandolf
