I put the line in the middle of the spool (after running it through line guide) and put a short piece of tape to hold it in place. No slipping. I do that on all line types.

 

It leaves residue when I take the line/tape off but it comes right off with alcohol and q-tip

You need something to keep the braid from slipping. Backing, tape or tying to the wiffle spool will all work. There's no mechanical reason I can think of to not tie to the spool, but something about it, I just don't like the idea. I use backing myself as I can't see loading a reel full of braid that will never see the light of day.  

On some reels the holes arent polished and have exposed machine surfaces on the inside where line normally wont make contact. Tying to these unpolished holes can cut your line like a razor blade. Tie to the hole, and then give the line a good strong pull to see if it will cut or not. The advantage of taping versus backing is that you still have plenty of line to flip it when it begins to wear and youll be fishing with new line again.

I always use at least a few wraps of mono as backing. 

using braid for the first time, reading this thread and stuff online as well. Lew's says to tie to the holes in the spool of Lew's reels, for what it's worth:

You can - but you won't use the full length, and it's much more affordable to spool up cheap mono to the point where you only put on 70-80yds of the expensive braid.

 

Also lets you get 2 reels filled with a single 150yd spool of braid instead of just one...so half the cost.
