OK, I am putting braid on a new reel for jigs, etc.
I will put about 40 to 50 yds of mono as a backing for the braid.

1. Do I need all that backing, or will less do as well?

2. What knot should I use to join the mono backing and the braid? Uni-knot? or?

3. What knot to use when tying on a bait.

I used to know all of this but the forgettor is working better every day. Thanks
