You know what's the worst? Getting ready for a Regional. Actually, any major tournament really. The conundrum for me is always picking what list to fly. I'm familiar with and comfortable with several, and they're strong in different ways against different opponents and lists, so picking one is the worst.
I'm down to a 2xU-boat/HWK list and a Palp Defenders list. I can't pick which, and of course there's always a third list potential.
When I went to worlds in 2015 I did this stupid thing where I didn't trust my gut, took something I wasn't familiar with and ended up paying for it because the list I took wasn't optimal. There's something about choosing a list before a big tourney that's twisting me about.
