I personally think teas are superfluous. If you're taking care of your soil and top dressing it routinely you really shouldn't even need teas. On top of that, it's been my experience that these teas tend to throw the balance of your soil out of whack more often than not. I've even found that it is in fact entirely possible to burn your plants with teas if you use too much guano and/or alfalfa meal.
The main reason people typically use teas is to re-inoculate old soil, but if your soil is constantly in check and full of microbes there really isn't much of a reason you should need to re-inoculate it you know? If you're set on using teas to re-inoculate your soil I'd recommend either a simple EWC tea for the job, although it's always much better to just plan your top dresses in advance and stay on top of them. I built my soil and have top dressed pretty much every month since doing so. Top dress with neem when in veg and top dress with crab meal in flower, this way within a few weeks they're nice and broken down and readily available for the plants by the time the soil is depleted.
I'd also recommend a product called Growers Recharge, does pretty much the same job as most teas will and will re-inoculate your soil. I use it every 2 weeks or so personally and I also use it to give my newly mixed batches of soil a jump start.
With living organic soil, your soil should already have all of the amendments it needs, so you should really only need to add EWC, EWC tea, or Recharge in order to keep your microbes alive. So long as the microbes are alive and your soil is always full of amendments from constant top dressing you'll be fine.
