Predator ll 800 spines

I posted a few days back about whether or not these shafts would be good out of a 35lb PSE Stalker Recurve..with a 24" draw.. What I neglected to ask,was what size feather I should fletch them up with..I was thinking 4".. again I have no experience with bows/arrows in low weights..all my arrows are fletched with 5"..what do you think is my best bet?

Like you, I like big feathers on my broadhead arrows for hunting. Assuming this bow will probably not be hunted, I would say the minimum size that stabilizes the arrow. I have 4" on some of mine and some have feathers cut down to 3". Both work fine if the arrow is tuned to the bow.
