Thanks guys, thats helpful, seems like its worth buying a plank. There is a company that will deliver a 6foot x6"x2" to my door for £50, only trouble I cant see it first , bit of a risk, but if its good should be able to get quite a few bows out of it. They say it usually straight and Knot free. Justin, looks like I got wrong info. on hardness from them though!!. should I risk it????h ???mmmm
