Not as well known as some but check out Schafer drop-aways including the MAT-1. They have been advertising a little more in some hunting rags but don't have a website that I'm aware of. They are located in Burnsville, MN. There were some independent high-speed video studies done with those rests as compared to others looking for stability at the moment of release and vibration after the shot. The Schafer was voted #1. I'll try and find some info. Also, they have their rests camo dyed at the same location as Mathews and Hoyt to match up perfectly. Not sure on Bowtech. If I find a website I will post. Cloud 9, MN you may have heard of them. The owner is a friend of mine who also has an archery shop. He is an engineer and has placed as high as 2nd in the world for IBO.
