Dan,
That's my Renegade 8 bow from OK Archery in Germany.
It has a three track x-cam design of its own with Duvawhoppi spreaders from Dave Barnsdale.
It's 36.5 ata, weighs 4.2 lbs and has a 7000 series riser for great strength and flex resistance.
Smoothest drawing and most accurate bow I have ever owned.
I have a second OK bow called the R8/40 on order.
It will have similar components and a 3 track cam system too but will be 40" ata.
