Looking at adding an indoor putting area in my basement.  Any suggestions on mats / aides?  
Was eyeing either a Big Moss mat or the Puttout system (aide and mat).
Any feedback on Puttout?  Seems hot now - but most new things are the 'best ever' until next year.  
Goal would be to groove/improve my basic stroke.  I can practice bending putts at my local course.  No need to add break/have anything overly complex indoors.
thanks
