guys, ive been on spiderjack and lockjack sport now for few months and man Ill never go back to hitch cord if I dont have too. as for the harness low attachment point being this thread was about that at first. I am going to buy a new saddle at the TCIA show in Hartford, maybe get a feel for a few and purchase w possible discount. but the function of pulling rope above your spider is a new thing for me and I like it, picture pulling above your hitch cord and not having to manually tend the slack, a lower attachment point with the spider allows you to pull more and direct the rope more in line with spider to self tend the slack. I am also using it up high at it's highest point on some climbs so I can just pull and pull as it will self advance, this makes it nice but you have to figure out what YOUR length is so you can reach it to come down still. So versatile to have different options of use. The lockjack sport is my secondary tie in option for double crotching as it is mid line attachable, even though it acts like ON / OFF switch I still prefer it over the hitch cord. everyday getting more used to some of the advancements! never thought I would consider a rope bridge but now seeing the benefits of use with a spider to keep the devise closer to you , you can incorporate a swivel and little more freedom left and right and adjust ability to fit your style. Thought I would share to you all! Climb Safe fella's!
