Its easy to spot the more sour limey ones you just gotta look in them bx3 and 4s, you gotta pop some beans tho. its the branchy ones that are stretchy that you want for that, those kinda remind me of the glue more. Mostly the thick slow growing ones are predominant in them 3sand 4s. You can pretty much top em once and tell which way they are leaning at a very young age by the way they respond. They are in there though.
