Everybody has their own preferences...What I like is a 00 colorado or a 0 willow on a 1/32.
A 0 colorado and a 1 willow on a 1/16.
A 1 colorado and a 1 willow on a 1/8.
A 1 colorado and a 2 willow on a 1/4.
These are blade sizes I like on a road runner....Would be about the same on a L arm wire spinner (beatle spin).
Some competive prices are at Jann's Netcraft on blades,split rings,and L arm wire forms.
Just a comment.The L arm wire spinner adds some "weed-proofing" to your jig and the fish do like them.
