I have heard of using troughs rather than trays to do big prints, as a matter of fact, a friend and I have tried (successfully) - it seems like this man devised exactly what we had to play twister and master juggling to achieve! If you want this size print, and you do it often enough, I'd say go for it!

And the "scrambling motorcycle prints" are worth it alone!

Cracking bit of kit, hehehhehe
