High rpm to me is 1000 rpm over peak power but maybe that's just me being afraid of breaking something and not being able to play again

Not sure I understand what you meant here? Are you saying if your motor peaks at 6000 then 7000 would be 'high'? It's really a matter of opinion I guess. I'm calling above 7500 high and expect to be there with my new junk.
