That's a false premise. High letoff to maintain a high poundage draw weight for older, ailing shooters does not work. It doesn't work for women or youth either. The shooter still has to drag that string back through the peak draw weight, and these modern cams hold peak weight for AGES before suddenly dumping them into the letoff.

This lie is something the high letoff crowd has invented in order to rationalize their own agenda. That agenda is having a bow they can hold at full draw for a long time. Why? Because they're a bunch of freakin' wimps that can't learn how or when to draw on an animal and keep from getting busted, so they want a bow they can draw when they spot the animal - before the animal can spot them - and keep it drawn until the shot is presented. Crossbow tactics, certainly, so why it so hard to understand why so many people call high letoff bows 'vertical crossbows?'

But, back to the question I want to address. Unfortunately, many people with existing shoulder problems are believing high letoff is the real deal, buying the 'miracle bow' that's going to give them extra years of shooting, then going out and finishing off their shoulders with it. The bow they were hoping would help them actually cut their shooting days shorter. Since there are exceptions to every rule, maybe a few people find the letoff does help them. However, overall, more people are ruining themselves with such equipment.

The ONLY way to make life easier on the joints is to reduce draw weight, pick cams that have a short dwell at peak weight, and have a steady, easy drop into the letoff. Yes, that kind of cam is going to cut arrow speed dramatically, but it's better to shoot slow arrows than to hasten the day where you'll not be able to shoot arrows at all.

IMO, this Concept99 bow is mainly for parting fools from their money. But, that's what most of the other products on today's market are geared for anyway. [:'(]
