I just changed the cams on my Alphaburner. I put the 7.5 spiral cams( I had 7.0 before) to get my 28.5 draw length.
I installed the new strings that came with and found that the draw weight has increased.
You'll notice that the cam sizes are grouped into families, denoted by different colors in the rows. And that any in the same family use the same string and cable lengths, and they also use the same deflection limbs. You just happened to move to the next family going from a 7.0 to a 7.5 cam size is all. If you went to 6.5 or 6.0 it would have stayed the same and the harnessing lengths would have stayed the same.
