dgmtrx, ... dynema/spectra is soft and supple and is ideal for the floatline(inside your tubing), not for your spearshaft. it'll knot up like crazy. 400#+ mono works like a charm.
rob allen makes a nice(easy&cheap) foam filled polypro line in any length you want. i have 3 diff float lines and i use that the most. mine's 40m.

your break away system should have your mono terminate in a loop close to the release/clip mech near your RA handle. go get a 1/8 inch piece of marine bungee(about 5 inches long), thread it through your loop and double it over on itself. when you're wrapping your gun, you should be able to finish your wraps by stretching back this bungee loop over the release/clip mech. your floatline should snap directly onto your mono loop(not bungee) and voila, tu es finis!
email me if you have to. i wish i had my gear here, but i have to wait till the weekend before i can hold my children.

aquiles has all of them in his closet. i'll take some pics and post them next week if that's not too late.
later,
andrsn
ps. riaan, no you never sent me pics of your floatline.

nor have i received the one you sent me.

i've discovered a new thing on photoshop so the website should be rejuvenated soon!!!!! seriously.
