Len, I have nowhere near the technical expertise as you, nor the resources you have to test these things. Since I am the source of the information that lead to your thread I figured I'd put my 2 cents in. I am keenly aware of the type that you are referring on AT. That site is a bit like high school when it comes to the brand loyalty. I always take what I read there with a grain of salt, but there have been a couple of threads over there about Guardian cam leanthat peaked my interest. One in particular where it was pretty evident that the originator of the post was not very technically proficient with archery equipment. All this poster knew was that at full draw the cables were touching the cam, which is only possible if there is some lean. Of course this thread eventually degraded into a bash fest and I lost interest. Other threads have had pics, one that you described in your post. Some of the pics show the cable touching the cam.

Ever since the Guardian came out I have been intrigued by its design and a fan of the potential it shows for where archery is going. With that I went to my local shop which sells the "Big 3" and asked how the Guardian is selling. The response was less than impressive and I asked if they knew why that was. The stiff draw was a main reason, but they did mention, without me baiting a response, that they had sent a few they sold back with problems. At least one had cam lean and cable problems and another had an unspecified limb issue. They said that this was enough for them to not push the Guardian, but they obviously sell it to those that are interested.

So, I'm sure that the majority of the Guardians out there are fine, and I think the design has opened the door for advancements in the archery industry. However, it does appear that some issues exist even if it is on a small scale compared to the number of bows sold. It's good to know that there are dealers out there like you that not only care about the sale of your bows, but go above and beyond to learn how the new designs work and find out if issues do exist. All things considered I would say that in the long run BowTech has a winner.
