Headstay size

[mikemosabe]

Hello all-
I'm replacing all of the rigging wire and it has been suggested that the headstay should or could be larger than the uppers. Referring to the Rigger's Apprentice and other similar vessels all of the shrouds spec out at a conservative 1/4" wire. Perhaps with a sloop rig it might be more appropriate but the backstay and the headstay angles are not steep by virtue of a boomkin and long bowsprit. She will be refit with a new roller furler as well. Any thoughts that going up to 9/32" would be better for the headstay? The headstay is about 41'.

Many thanks!!
