I'm all about my ass covering mate, thanks for your concern. Last thing I want is to have some unwelcomed problems.I read the whole thread. You don't need to repeat yourself. I raised legitimate issues. Ignore them if you wish. The fact you didn't know what HSE stands for until a moment ago is telling for me. I'm not saying don't do what you plan; I'm saying make sure your ass is covered, but it's your choice. Slainte.
