3 link/4link

[Rocket Man]

Does anyone know how to get hold of the people from Lateral Dynamics? I have left phone messages and emails with not a return? Is this company still in business and can anybody share how they are to deal with>? I know they are a sponser on this site but how can they advance and succeed in business if you can't get in touch with anybody from this company?
Can anybody share what they are like to deal with and what is the latest consensus about the DSE 4 link Vs the 3 link? At least DSE will answer the phone.
I have never read any real in depth reports on the Lateral Dynamics piece. I have found some information but nothing real technical. Perhaps I missed a thread and need some direction.
Thanks
