If I were to do it again I would make a serious attempt to find the flat, unwaxed version of the lacing. Check to see if Poly Fiber has that. The round lace causes additional effort when placing tapes on. It likes to have air trapped. I have been building up the glue over my laces to make it a bit better. It seems Im not trapping air but it would definetly be easier if they were flat. They say you can strip the wax from the lace, but again thats more work.
