i ran shelf domes on my 392 and did fine everyone is usually gonna recommend custom domes but if your not looking for every last hp and just something to ride i wouldnt worry about it granted they only cost 10 bucks more.
that's was about all that stayed the nights. But gotta also think, if everyone thinks like that no one would show. There was more peeps at the hill then what was in our camp for sure tho.
