What is the best stiff shaft for a Taylormade fairway wood?

I have a Taylormade 08 Burner 3 fairway wood, but it has a regular shaft in it and I need a stiff. I really like the club so instead of changing it I want to change the shaft. Any ideas which one to get?|||I have the same club, but to be honest, I would just sell that club and buy one that has a stiff shaft in it. I did this and I am so pleased with the results.|||TaylorMade Burner Superfast 2.0 TP and TaylorMade R9 Bois de parcours is pretty great
