I recently bought a 2008 model copper johns dn2 supreme sight. it is extremely well made and has 3rd axis adjustment. I really like the sight, but it doesn't look like i can use it on my gto, the pins won't get close enough to each other. The pin design looks to be a bad idea. they have wide bases that run into each other. to be honest i can't image using it on a bow over 275fps, if you want 20,30,40,50 yard pins.my first pin is set at 20, but my next pin is set at 36yards! do to the bad pin design. i was wondering if anyone else has had this problem with this sight on a speed bow? right now i have set my pin at 20 yards 2inch high and also use it for the 30yard pin, which is about 1in low. i have owned TR,cobra,extreme and several others in the past and never had this problem before. what do you guys think
