There are truly useful pulley and ratchet systems available in most climbing shops. Big wall climbers have developed strong and very light systems for hauling loads on multi-day ascents. I use an antique Hiebler clamp and a pulley on an oval carabiner. Climbing gear and clothing has many crossover applications for hunters.
