They will be completely fine. I think much like @LeanderMommasaid in the Austin reginal form, going early, especially considering how hot it's been recently is probably not a super band thing anymore. Considering they have been on a role recently; they should easily make finals. It's much like how Cedar Park was both last year and this year, and they were 3rd in both prelims and finals. I think bands are going to start to realize that going earlier, especially in outdoor venues, is not as bad as people make it out to be.
