Well, you see my personal favorite is the pink buffalo strand. They still taste the same as the rest of them, but the high is favorable! I have to say the most easy for growing is the B+ strand, but I like the way the pink buffalo strand looks, and they seam to grow bigger (also much, much heavier than all others, and remember mushrooms are sold by weight) than all the other strands. I myself am no expert, but I have read a lot, and think of myself as moderately knowledgeable in mushroom cultivating... I have herd that the "shroomery" is the best place to buy spores, but I like micro-supply.com much better, they are cheaper and I find the strands easyer to grow, and they seam much more sterile to me... (but you might want to see witch one you like more)
