Since there is no type of ranges &greens for warm up .May I suggest setting up some type of practice area that you access by credits for a specific amount of time ie;15 min- 30 min Etc. & charge 1 credit per min. of practice time! Where you can use all clubs &situations to improve your game .chips,wedges, sand, greens . You get the picture lpease comment & let me know what other WGT members think. Thanx Leadvillebob
