RE: Opinions on shoot-thru style bows or bows without cable guards?
Nope, not mine. Just a picture I was able to find on the net. I have shot X system bows by Martin considerably though, I live very close to and personally know Jim Despart who has won in vegas, NFAA indoor and outdoor nationals, etc. He is the inventor of the X system and co-owns the patents with Martin on them. It really is a great system, if more people had exposure to other types of competitive archery such as indoor spots, outdoor FITA, and field archery they would see these types of systems more often.
I am not familiar with the bladerunner system. I would be curious to see one up close though. My initial impression is that there is a LOT of moving parts on it, but it may be a great setup?
