Yea i can do the first trade now. Dont worry about the Gyarados, im thinking Shiny Charizard Mild instead!?!
In terms of the IV spreads im good at Adamant, Jolly or Timid as i have those synchronisers. I can generally get very good spreads, but i tend to use low frames to make it easier. The main reason that the Volcarona has a few low IVs is because i wanted that HP on an easy to hit time, but generally 3-4 31's and a couple of 30s is easily do able.
