I think a 110 is only going to work for a very quiet band.
A 210 will work for a lot of UK bands that aren't hell raisingly loud just doing vocal PA. Unamped drums with guitarists that are onboard is the new world order.
As for monitoring and going through the PA... all power to you if the 110 is pointed up to your ears, drummer can still get a feel, while it doesn't mess up FOH sound.
