Anyone fish this rod that could recommend Skagit Flight head grain weight, ballpark? I have built many of the 11'6" and 12'6" models as center pin rods but am doing a spey build on one this go around.

Have a 625gr. head that is definitely on the heavy side, despite the rod's faster action and shorter length... Seems a 575 would be about right, but don't want to purchase what I don't need.

Any suggestions would be welcome.
