Have you been to both? If so, you have a better basis than I.
I've only been to Lafayette, and the food/people are absolutely amazing. I would not mind sharing conferences with them for the sake of LaLa road trips. It's crazy awesome.
I've never been to LaTech, but I've heard their facilities are atrocious. I vaguely remember some football success 15 - 20 years ago (WAC title?), and they have Terry Bradshaw to hang their hat on, but what else? I don't see or hear of any commitment from their AD, so maybe that's why none of their conference brethren seem to give them a voice/vote in discussions?
I've been a little out of the loop lately on LaTech, though; if we have any Bulldog lurkers: not trying to flame you! Feel free to update me and make yourselves feel better.
