I have made no effort to hide the fact that I likes me a good massage and I hope that I have given a few to some of the ladies (shhh.)  But, every now and then, I see open-ended requests for suggestions on here.  Hard to give since personal tastes vary so much.  

The OP specifically asked about AMPs, but on the oft chance he is open to indies, agencies and traditional AMPs....

Independent ladies - Michelle always comes to top of recco list for mature, good full range mix of services.  You can find ads for the following ladies by searching BP (gasp) Casey is just plain fun, but not necessarily too therapeutic.  Nataly is quite good at therapeutic. Empress is a good choice if you go for AA spinner builds.  Kim is good AA choice.  All these ladies have their range of services listed on their TER profile.  There are many others, some of which prefer to remain UTR and some I have no personal knowledge and will leave to others to suggest.  And apologies in advance to some ladies as I know I am forgetting many.

Agency - I never have had, nor heard, anything but good things about exotic atlanta or journey2u.  But, not exactly therapeutic in the traditional sense of massage.  There is no comparison in terms of looks for these ladies to AMPs however.

As for pure AMPs, again - The ones I know that are good, albeit no extras, would not want to have their names listed in forum.  Go to BP under therapuetic massage and check out Johns Creek area if legit is what you seek.  If AMP rub and tug (or more) is what you seek, the ladies change so frequently that it is hard to give a good suggestion - but options exist on Buford Highway and on Piedmont.  The advantage of these areas is that if you go and don't like what you see - there are other AMPs to choose in same general vicinity.

Last bit of advice, there are a few reviewers that have developed very good reps in terms of giving solid info - cdav and jspikes before him come to mind.  (Damn, now I am shilling for dudes - I need to retire.)  Just my opinion of course.
