Gwalt, one of the things that I think we would both agree upon, is that the sort of sidetrack that you made, probably should not have happened.
IMO, a dealer whom we rely upon to confirm product synergy should supply with you exactly that. If they fail to do so, inadvertently or otherwise, it would generally lead one to concern. I know in this hobby that there are endless possibilities, like you said, but I am always concerned about people in the industry who profess knowledge, and either have it and lead you wrong ( for their own agendas), or simply lack the experience that they posses to have. I rarely talk to any dealer these days who will contemplate that there may be consumers out there who actually know as much or more than they do! A pity.
