I only have so many vacation days available at my work (something like 3 weeks or something). With the new baby coming, I really should keep as many as I can for right before and after the birth to help my wife out and spend as much time as I can with the new baby.
God willing, I'll be able to go next year though. :)
Yeah, I was unsure about responding to your post because I've literally never used DPunch. I always use Superpower for Adamant and Hammer Arm for Brave just to score guaranteed 1HKOs. In my personal opinion I would suggest 4HP / 252 Atk / 252 Spd, if you're using Adamant and 252 HP / 252 Atk / 4 SDef if you're using Brave. Reason being, your HP is going to drop every turn and there's nothing you can do about it. You would most likely be best served by trying to squeeze in every 1HKO possible as fast as possible.
Firstly, I do a completely new runthrough for each roamer I do. I don't know your standards, but when I couldn't use AR it only took me 20ish hours to get to Tornadus again (JPN black) and with AR it only took like 5 (lol) hours to get to Thundurus. But as for RNGing it at the E4, I seriously don't think that's possible because the last battle would advance your IV frames at like 60fps. :((((((((((((((
