well, I can't speak as expert on spin handling systems, but on the subject of retractable dog leashes, I'm THE MAN.



No brand names have ever stuck with me, but you certainly get what you pay for with these things. there can be a remarkable difference in quality for that unit that's $5 more expensive.



stay clear of the kind that have their own 25' cord, it'll be useless to you. the cord is springy as heck, and the clutch mechanism won't hold up for very long.



look for the "big dog" variety that use the 3/4" webstrapping as the leash material. these have durable clutches, and you'll have the spool capacity and recoil spring strength you'll need for your halyard. before busting it apart to remove the webstrap and coil your halyard, buy yourself a cheapo tape measure and take IT apart first. you'll be better prepared when the spring flies across the room.



also pay attention to the clutch button mechanism. they each seem to have their own take on it, and some of them are just awful. you obviously won't want something that releases simply by bumping it.



unless this is something you want to get done this weekend, you can probably get a better price online than you would at petsmart. go to petsmart to play with them and figure out which one you want, then go to the dr foster and smith website to get a better deal.
