gmoses: I guess a better way to do this is to ask your budget for substrate. What's your ideal price point?
I think ADA Aquasoil is the best product out of the ones I mentioned. But you'll have to endure a month of cycling. Which isn't a bad thing - running a tank for a month before adding shrimp really benefits them and allows their environment to be nice and established before they move in.
if your kinda in a rush and need to go on the cheap side i have been running fluval shrimp stratum since feb and added shrimp right off the bat. i did have alot of moss and things from other tanks in there for the biofim to start them out with. and it has worked well for me
