I was considering a COR3, but brought a TORQ instead. I think the short splice is more than a gimmick and feels responsive in the hands. Apparently the COR3 has a lower middle than the TORQ but I'm not complaining as the bat is fine for driving off the front foot.
I've taken the shoulders down an inch on a eBay bat to see what effect it had on pickup and it felt alright.
I have Newbery Uzi and know the finish will be good, but I think the Mongoose would be good for t20 and more forgiving and possibly a better discount. Mind is Series (grade 3) and it should be available for a good price.
Now that is my opinion based purely on reading reviews and watching YouTube. In Australia we can't get either brand and are fed a lean diet of Kookaburra, GN, GM, Spartan and Puma.
