Do you spool your reel with mono before braid? If so how much.  This would be for any top water rod.

 

also does it hinder anything?

Nope.  I used to but now I just reverse the line on the spool every other year or when it needs it.  Now I only use a backer when I have a partial spool of braid to use up.  I don't have any problems using a backer. Just easier for me to flip it and less knots to worry about.

I use braid for all topwaters except buzzbaits. Fill the spool with more braid than you can cast off on a long cast. I fill mine with almost all braid, just a few wraps of mono backing.
