Muzz,
Here's a quote from a guy on Atalk (Evansarchery) about some of the new BowTech's he got in at his shop.....he mentions cam lean.
I have shot The Defender, The new Tomcat, and The Independence. So far I am very impressed by these 3 bows. I had to check my shop scales when I drew the Independence, I could have swore it was about 60 pounds, but it was on 71!!! The smoothness is unmatched, even smoother than the Liberty! I also checked the Defender for cam lean with our laser and found very little if any. I was sceptical at first, but not anymore. I think this will be a banner year for Bowtech.
There is an indepth post somewhere that I need to find that explains how the weight distribution on the "E" cams by design does not promote excess cam lean.......I'll see if I can find it.
