Purchased in early 2024. I used this regularly, swapping with my 16mm I bought 6 months earlier, playing an average of 2-3 times a week. I buildup my handles because the stock ones are always too small - the original grip is under the blue overgrip and virtually new. Lead tape has been added, and covered with black fabric tape. Nothing wrong with the way it plays, no noticeable core crushing (using the "two thumb" test).
