I have considered changing the diamond system. I have the turnbuckle thats used on the Tiger and Fox. Its attaches to the front of the mast instead of the sides. The upper diamond attachment location is the same as a F18. I can't see how the spreaders are that much different. Comptip will always be a problem but the prebend in F18 masts is below the hounds and below the comptip. Measured at the spreaders.
