When it comes to Legendaries, do you prefer soft-resetting for good IVs or Hyper Training them? The former makes them feel more "legitimate" (and future-proof), but getting a Hidden Power type is a nightmare.

I've spent weeks SR'ing Mewtwo in US/UM, and I've rolled a Timid with 31/12/5/31/31/31 and am debating on whether or not to keep it or try for a better one. Advice?
