Hey BB,
Just buy a spool of 4lb Floro and be done with it! I'm a mono guy as well and have developed a real fondness for this line. Yes, it is expensive, but it will outlast a normal mono line.
Virtually no line stretch, invisible once in the water and holds up to cold temps very well.
Also, it is very much abrasion resistant, so the Erie zebra's won't cause you grief at all.
I have been using floro for a few years now and it has held up very well, from summer fishing all the way to -35 up at Temagami (Which has no fish of course!)
