Dont do it mate, they are rubbish, I have one and decided on getting a losmandy G11 for mounting my SN10 and TAK TOA130. It now sits in my garage gathering cobwebs. Once you have tried a decent mount you would NOT go back to the LXD155 mount.
They are cheap yes, but in all senses of the word. Honestly they wobble like jelly. Need to be worked on and generally definitely not suitable for a heavy scope. The only plus with the setup you are considering is the stainless steel legs.
I know I might cop flack here, but I am talking from my own personal experience.
