There are lots of sleds on here with the exact set up. My friend has a 155" Dragon on his Edge, you have to put some 7 tooth 2.83 pitch drivers on it. 7 Tooth because the 2.4" Dragon wont fit the tunnel clearance, unless you use smaller drivers or trim the track 1/4" on all paddles. Im putting a 153" Attack 20 on my Gen2.
