Selecting shafts for fairway woods and hybrids

Hi guys,

Anyone has a general view on how to go about selecting the right shaft for 3w, 5w, and hybrids?

Does the shaft weight have to go down as i go down the clubs, i.e. 3w heavier than 5w?

spin levels? Being innocent here, but I cant understand why the woods need high spin levels. Shouldnt the ball not balloon so it gets better carry?

Just as a reference, my driver clubhead goes about 105 mph.


Any thoughts?
