You need one. I didn't think I did. I could get by with rope bungee straps and tie wraps. Then I dropped $50 at the local gunshow on a 1000' spool and now it's all I seem to use. It's nylon so you can cut it wih a hot knife or regular knife and seal the ends with a lighter. It's impervious to sunlight, swimming pool chlorine dirt, salt and a ton of other chemicals. Once you learn to tie a better knot than a square not it will hold. If you want to spit the cost you can get an empty fishing line spool from academy. The 4"x4" ones seem to hold about 300 yards. So you can split the cost or split the spool up into manageable chunks. Maybe he best part is its so cheap you don't have to untie it. Just cut it and throw it away.
My next spool is going to be black because the wife is not too hot on olive green.
