converter opinion question

Thanks for all the input. It is great for for thought. I actually like to hear the differing opinions. I'll probably hold onto the 2800 converter and give it a try at some point. I have a bunch of rear end ratios from 2.94 to 3.91 available, as all my Dodges have 8 3/4 rears, which makes trying them out a lot easier. I might even be able to give some of AJ's mileage ideas a try by varying the ratio on a series of trips. I really appreciate everybody's willingness to give me your 2 cents. I'll try to remember to post stuff here when I try things out.
