I'm surprised the most conventional option is winning.
A handcrafted wooden gun in the size of 90 will have so little difference in performance compared to a conventional 90cm aluminium gun that it is hardly worth doing it in the first place... The advantages of wood (high mass, oval shape, open muzzle etc.) make a huge change in double band and longer guns. The performance of a wooden twin-band gun in 90 or 100cm length cannot be compared to the performance of the same gun in aluminium...
Give it a little tought before voting guys...
