RE: GP Christen Eagle engine
I had no problems with performance of the DA-50 in my 19# 31% Edge. And it was still in the breakin preiod. Considering what GP shows for engine installation, I guestimate that my CE w/DA-50 will be about 17#. The 60 may be a bit much. A DA or BME is perfect! Good luck whichever way you decide.
