hooked4Life, You can get the Spectra 150# from Amazon at a really good price. Get the 1500 foot spool, I got the red color and really like it. Here's how I spooled it on: Make a clean cut on the end of the wire, make a very small loop, and crimp, mash the loop with a pair of pliers until you can barely get the Spectra through the loop, you can use any good knot to attach, it will never come loose or slip because it is compressed. I then used a piece of scrap plywood, drilled a hole for a 1/4" bolt, then bolted the spool on using a large diameter washer, also used a nylock nut so the pressure adjustment would not change, I then used a portable vise to secure the plywood, but you can also have a person hold the setup. With the spool setup directly below the tip of the downrigger boom (downrigger is mounted on the boat), I then spooled 700' of Spectra over the wire using the line counter on the downrigger. Then repeated the procedure for the second downrigger, I ended up using the entire 1500' spool. Use a leather glove to guide the Spectra on the downrigger spool so it is level, also adjust the nylock nut so the Spectra is wound on very tight. I am very happy with the Spectra, quiet, no hum, easy to handle, I'm sure you will like it too. If you need any other help let me know.
