I have been researching the Coiltek nox 10x5 elliptical dd coil to use with my 800, I have read great reviews on it, so I thought I would run it by you all to see if any of you have had or used one and what your thoughts are on them? I have the 11" an the 6" coils for my 800, Oh I haven't asked the wife yet if I can buy one so I hope she don't read this Thank you.
