I was so impressed with my GN50+ that i decided to get a copy of it made by B3 in lower grade for net sessions. After contacting B3 via email Streaky sent me couple of profiles similar to my GN50+ in long blade. B3 is more closer to a Laver Ultra than GN50+ but exactly the same as shown by Streaky in the pdf. Pickup is balanced but definitely not light as GN50+. Ping is awesome as expected from a bat of this size with a stiffer sound due to 4 grains and B3's "Ready pressing".
