tsunami pump is not a necessity. it does take about 10-15 minutes for the 750's to fill - crack a beer, relax, or make sure all you gear is working. i also use that time to stretch out and warm up my muscles, as my body hurts bad the next day if i don't.
why would i wanna carry my 400's and swap them out if i have 2 750's in place of them?
