Alex...on a bugger it doesn't make too much difference (personal opinion). When I tie small buggers (12-16) I sometimes strip one side of the feather and this will help the hackle line up in the same direction ( I am kinda lazy at times on buggers about making sure the hackle lines up correctly also). I personally dont worry about it on buggers (on dry flies that is a different story). This is also something that you get better at with practice. You should also check out Al Campbell's fly tying series here, I have been tying for a few years and frequently go back and read the articles for tips that I may have missed.
