Thanks for the positive comments and support chaps.
Lone Racer - Yes to all that, temperature variances are extreme and do cause distortion, I am hoping to get the whole thing into a bedroom this year and let the wife have her conservatory back! Funnily enough I'm the only racer in my village.
Bleep - Thanks, afore-mentioned wife keeps saying this about size, but I don't quite understand......
Rob - I am honoured to have your approval, I love your site and often refer to the reviews when contemplating a new purchase.
Cheers
Dave
