£1600 should just about buy a 1970 Marshall JMP Plexi with 4 by 12 cab... funilly enough I know where you could find one... Actually by the 1970 it no longer has the plexi front but still is the same animal
Though for one tenth of that you could have some nice Yonex C280 irons
As to what. Whatever suits you best. But I'd go CF at one of the Nat fitting centres. Preferrably one that has a number of different makes of club there.
