What size spinner are you guys using for this kit.
I didn`t see it in the manual unless I over looked it

Lee,
I just finished my new H9 Extra tonight. Will be maidening her, this weekend, weather permitting.
I too was undecided on what size spinner to buy. I went with a 4", and I'm happy with the looks. You could go with 4 1/4", but any more than that, and I think it would look wrong.

ive seen anywhere from 3.5 in (what i have and a few other on old extra) to 4.5 in. whatever you can find or afford.
