Goat tuff or fletching tape if it’s new. I wouldn’t use fletch-tite again. I did in the 90’s but never again.
Where are you buying your feathers? There is zero comparison between processed feathers and natural, unprocessed feathers from wild turkeys. If you want the best fletching you could glue to your arrows I know a guy. They’ll last you many, many years with zero maintenance and laugh at rain.
