this is one of my things that just don't end up great....and I have done it lots. my big issue is getting the bar end so there is enough for the plug to cover neatly and completely and getting to much so the plug is tough to get.
I have accepted that this is going to be one of those things that i keep working on.
I used Lizard Skin for last wrap... very comfy, but wears really quickly
