I typically order rope (it's not a line until it's cut from the spool, but that's just a technicality) from:http://www.apsltd.com
I just ordered all new lines all around earlier this summer. This is what I ordered and I am extremely happy with the feel and handling of the lines.
Main: New England Ropes Salsa 8mm 42ft.
Jib: NE Ropes Bzzz line 7mm 32ft. (I would recommend 6mm but I didn't know that then)
Aussie jib halyard: NE Ropes V-100 3/16" 70 ft
Main halyard: NE Ropes Sta-Set 3/16" 27 ft
Jib travel cars: Marlow Excel Pro 5mm 12 x 2 (different colors)
Everyone will have their own opinion. This is merely mine. It's not the cheapest setup out there but I really like it. World of difference over my old lines.
