Did a quick search online. Seems a lot of people use it in conjunction with honey. I'm sure it would turn out fine with just the agave, but man is that expensive! If you have the money to get the amount of agave needed for a straight agave mead then go for it. I'm sure it'll turn out well. As apache said though, just stick with the SNA schedule and it should ferment out just fine.
