Had a look at Simmys 2 bats today. I don't think the pictures do them justice, look much nicer in the flesh. Profile wise, when I stacked it against my 666, it certainly had a lower middle. Not so much in edge profile but the spine height was higher at the bottom but not as high going up the bat in comparison to my 666. It's has a little more concaving but not as much as I see on most bats. The pickup didn't feel great but Simmy partly cured that with a thick spiral grip - felt better balanced.
Didn't get to see much of it in action, Simmy hit a six early on and then changed bat as the oppo seemed be using a concrete ball (which we got changed later on).
