Where possible R1NGAs suggestion would be the best option until I can get over to the Empire HQ and sort out what Bill would like to do. He does know about the problems and I believe he is having some risers made out of stainless steel, but I last spoke to him back at the beginning of December, since then I have been away on holiday for 3 weeks, then christmas, then away for my wifes 'big' birthday, then a funeral 200 miles away, and a business to run as well, so sorry if things have been a little slow, it's not Empire's fault, but me who hasn't had a chance to follow things up yet. I never was good at multi-tasking I'm afraid.
