I did not object to anything Rick. What I asked for was your source information to make assertions of cost savings and performance for either. You make claims for both. Unless you can provide numeric rationale for either, you are being speculative for both and have no firm basis for those assertions. I look forward to your numbers. If you are unable to provide any, then your suppositions for differences and similarities have no basis other than noting physical differences. Show me the cost saving you mention. Don't just say there is one. Show me the costs. I'm from Missourt on my Mother's side so I need facts that support statements. Thank you. D
