I'd recommend reducing the angle of your primary to 15 degrees or
less... in fact a flat primary may actually work better at the power
level you're planning. As described with the 45 degree primary, you'll
run into two problems. The coupling between the primary and secondary
will be too great, and you'll also get strikes betwen the top of the
secondary and the primary. A "flatter" primary will solve both problems.
