Reviews
Average Ratings Based on 1 Customer Review
Hot as fire. Almost unfair out there. Don Ellis Player
Pros: Super jump off the barrel. Short break in time. Hottest bat in my bag. Thinner handle. A combination of a thinner alloy and not much flex at all.
Cons: Wish it was just a little harder. I got a saw tooth crack in mine. Bat lasted about one season. Do not use this bat in batting practice. The bat is way too good to waste swings not in a game situation. Wish it was a little more durable.
