Where do we go from here?

I tend to like OSB, I know it is not everyone's cup of tea. This probably goes back to my father who was a carpenter and OSB would always be his material of choice for something he wanted to last. I appreciate it is heavier, and harder than ply but is also stronger, more consistent and more stable so 11mm OSB will give greater strength than the 12mm ply and only be slightly heavier. The fact that it is a lot cheaper than good quality ply is also a consideration, and I gave up buying cheap ply many years ago 

 

My alternative would be MDF, another heavy option, but doesn't have the strength of OSB
