You're an enlightened man, bfisher. :lightbulb
No doubt, cam lean leads to premature limb failure and shortens string, cables, and component life !
I now shoot 3 track bows exclusively and haven't had to deal with cam lean for the last 9 years. :thumbs_up
Enlightned? Not really. Just been shooting compounds bows for almost 40 years, recurves a few years before that. It doesn't take a rocket scientist to figure out that bow limbs are designed to bend in a straight line and not be twisted. On standard vertical limbed bows the limbs flex backwards and return in a forward motion when shot. Parallel limbs travel more in a vertical direction, toward each other, but in both cases supposedly in a straight line. At least that's the theory.
Take a look at any recurve or long bow. It's pretty much assumed that any with twisted limbs is junk. Yeh, it might still shoot, but..... Why would a compound be any different? Twisted limbs mean lateral nock travel; strings not tracking straight in the groove because the cam is leaning; same thing for the cables; servings being frayed and/or cut because the cam and module tracks are crooked. The list can go on and on.
Some will argue that it's not a big issue. If it isn't then why are companies now trying to do something about it. Because, IMO, it hasn't become a big issue until the last few years as bows got shorter and shorter, limbs got shorter and shorter, and cams have gotten larger and larger. I think certain companies are searching for answers to some of these issues. Then they'll have something to sell next year or the year after or...........Then there are those who, just like their most loyal fanboys, are still in denial about it rather than just facing up to it.
