Thank you for welcome! The USSZ are made by Zafar in California in the USA. This was custom made for me a couple of years ago and is my go to match bat. It is USSZ's top of the line bat and has absolutely blemish free willow, no concaving, thick edges - really nice balance. Can post more photos and exact specs later today.
Of course the ST is the best looker and was bought from Sudeep - custom made in the Avenger profile. I owe a review on that one too. Have played just a few games with it and that bat in view has not opened up completely yet. Great workmanship on it though.
