Thanks everybody, I decided to go with adjustable Forespar one (bit dearer here in Tasmania $225) as it was the easiest for me and using a roller reefer I am able to adjust length for reefed genoa if necessary.

My wife and I have just brought a 26M but sailing dead down wind I cant keep the genoa full, I used to sail NS14s (a 14 foot skiff that doesnt use a spinnaker but we had a jib pole for this purpose), does anybody use a jib pole on their Mac26? if so what length and what thickness aluminium?
