I haven't seen Ava, but Cherry is great.  I don't know if you're actually comparing apples to apples here.  One, Ava, is petite and very young.  Cherry is considerably older and a taller, more muscular lady.  I wouldn't call Cherry big, as in heavy, but I wouldn't call her petite, either.  She's got a great body and a flat stomach and she DOES KNOW HOW TO TAKE CARE OF YOU.

Ava is still on my to do list.  But you can't go wrong with Ms. Cherry!  She does enjoy her work!
