Something weird is going on with my game.. I do my normal warmup routine at the range, hit about 30-40 balls then i took out my mb 3 iron.. I flushed it 20shots in a row.. Swings going great about 60balls in now, then i take out the hybrid and snap hook the first one. After that ball.. I couldnt even hit a 6 iron.. Should i stop around 60 balls? Because i have no clue whats going on, and it happend very often.. Almost every range session. I cant seem to miss at first, even an mb 3iron was amazing.. Then hit what seemed to be a brick wall and could not hit anything for the next 50 balls.. Any advice or even a hint to know why this is happening? Thank you for any responses.
