i would like to see a large putting green that you could practice on. Maybe an option as to where the player stands then the option to choose your aim point.. also the availability to hit like 20 or so putts from each shot.... A driving range option would be sweet also... maybe you could allow the country clubs the option for one that would be included in the startup cost. but basically each range session is a sm. med. or lrg. bucket option and the range would extend to 400 yrds... give the option to select wind.. dont forget the option for short game practice in the practice arena...
