I just shot my first 800 series at the age of 67. I had almost given up on ever shooting one. It was getting so late in life to do what I could not do in my prime. I have always carried a fair average. Currently 214, but the new equipment changes the lanes so drastically that it is hard for me to be consistent over the whole night. I start out good, say 240 or 250, but it goes downhill from there. The lanes dry up and I am moving left the rest of the night. But on Thursday I got lucky and did not have to move. If there is a best article or book out there to teach this old dude to make the proper adjustments, the way to get it would be appreciated.
