My Daughter had similar testing numbers. Both bats where 33/23.i'll share the info from the one player on my team who has tried the Unlimited.
She did exit velo testing with her Dual stamp and GH ADV. both in 33/23. and avg was 66-67 MPH over 10 hit balls with each bat.
The Unlimited she tested is 34/24 and average exit velo was 70mph. so 3-4 mph faster.
