I followed advise from many, but most thanks to woodyoulike. I opted for Elka brushed and oiled 22mm planks with a 6mm oak layer. Must admit im very pleased with the finished look. I do however have a further few questions. 1) Elka provide a treatment called Elka protect which i have used over the floor as per their advise. It does however feel very much like a linceed oil. Could linceed oil be used(much cheaper) 2) they also state not to use waxes on the floor. Very strange as i thought a wax would be ideal for a wood floor??? Ill post some pics when i download from camera.
