I've used chinchilla sand for my LH cream satin boy before, and, especially during the summer he seemed to enjoy it, as it remained cool, so you would often see him 'lying on the beach'
It was easy to clean out the wet corner and certainly never got caught in his coat.
the issues I had were the weight of the cage with the sand in, and when trying to give him fresh food (I had memories of my Mum feeding me ham sandwiches on the beach and crunching on the sand - yuck).
I've found megazorb is not great for long haired hams, to be honest, and much prefer finacard!
