spooling a new reel with power pro

[bloocrab]

About 5 turns of monofilament line, I use 15# to try and keep the knot-size down, try to bury the knot as you reel - you don't want the castable braid finding that knot...

Some guys use electrical tape but I find mono works better. Without some type of backing, the entire spool mass may spin on ya...definately use some type of backing IMO -

When this generation of braid first came out, I didn't realize that I needed backing. Lemme tell ya, I was scratching my head for most of a Saturday afternoon. Why can't I get those schoolies in? Now I put on enough mono to cover the spool and the schoolies waterski.

I use tape on the arbor, as Bloocrab mentioned. It is just enough for the bitterend knot to dig into. No problems so far, but haven't had a big fish take me down to test it... Tried it with backing, but the knot bugged the chit outta me, everytime out.
Also depends on the spool size and how many yards/$$ you want to put on. Packaging size is important. So, will a 300yd roll of 50# PP fill you up, or are you going to have a 75yard cut off???? Can be more economical to have it spooled in a shop, because it kills me to waste that much. I wish they would just sell it in 200-250yd increments as well. The 150yd packages work for me on 4000 class schoolie reels only.
