It should be but there is the issue of SS amps muddying up after 5-7 on the volume. My buddys have two 100 watt'ers and half stacks and have them set at 5 and its a perfect mix and you can still hear everyone fine. Also the drummer can still really be heard over the amps.

So 65 might cut it, it might not. It all depends on how far you can take it...
