I've used Omega HotHead Ale yeast in 2 brews last year. I fermented at 79F with no issues: a 4.3% Session IPA and a 6% Rye Ale and both came out very nice. It ferments agressively, fast and yields very nice esters even at 90F and beyond.
I have friends who brewed with it and was similarly impressed. Also, you will find enough forums on the Internet, with brewers whom have used it.
I really hope the next dry yeast released on the market to be 1 or more Kveik yeast strains. It's truly an amazing yeast to work with. You can make anything from IPAs ( even dark ones ), Pale Ales to brown, stouts, reds, bitters and even light Belgian styled beer, most likely with the appropriate strain ( some strains do mimic a belgian phenolic, fruity profile ), the right fermentation temp., grain bill and possibly some spices, if you're into that.
So, if you want to use it, just go ahead.
