Definitely no safety issues as Mesa transformers are very tolerant of impedance mismatches. But there's always a loss of efficiency, attack and articulation running a 16 ohm cab off of a Mesa 8 ohm tap. Moreso than doing the same on Marshall amps IMO.
Didn't Hetfield run his IIC+ into Marshall cabs? Aren't those usually 16ohm?
