One of our 14yo hit one out with a 2015 last weekend. Her first HR, but she is about 5'10. My daughter swings the 1b and at 5'3" 110lb has hit them farther. She likes the feel of the Whiteout as a utrip, NSA bat. I will see if she can take a few swings with thr Xeno at our last practice before nationals and try to give some feedback. Havent seen many in use yet.
