Unfortunately we don't have a practice ground as such at my club. We do have a practice range, but then you are using grotty one piece range balls that only go about 3/4 of the distance of proper golf balls, and you are not allowed to walk out to check your distances anyway, due to 'Ealth 'n Safety considerations. However I was able to work out my distances out on the course by trial and error and using a GPS watch. My longer irons have a 'speed pocket' to give a hot face. Only problem with this is that if I hit a ball exactly off the sweet spot it goes about 20 yards further than normal!It took an hour to work out yardages on the practice ground using my GPS device and taking an average. At my level that's as accurate as I need it. I could go and get on a launch monitor but don't feel it necessary. Just because Delc got bitten it seems he needs everyone to suddenly fall into line and have an industry standard. That won't happen and each off the shelf model has its own set of shafts which will give different results with different golfers. You'll never get two clubs even with equal loft going the same distance if there are variables (shaft, perimeter weighting, forged v cavity, hot face)
