Hello all, I have a question, wondering if someone can help. My clubs seem to accumulate quite a bit of "golf mat residue" after each session at the range. See picture after only one trip to the range ~100 balls. It's not particularly difficult to remove the gook, but more importantly, I'm wondering what it may say about my swing. For you sub 10 indexer's, does this happen to your clubs too? If so, more or less than the picture shown? Thanks in advance! Greg Index: 14
