I recently purchased and returned 2 Custom Pro SLP's. Both were extremely clunky to crank out of the box to say the least. After returning those I went to Dicks to try one out there and both the ones they in stock had the same issues.
I was extremely disappointed as I own two Tournament Pro G's from 2016 and two Pro Magnesium's from 2017, all 4 are running smooth as butter after years of use. I winded up trying a JDM Metanium and a Scorpion DC instead, so far I've been very impressed with their quality / smoothness.
I might give Lew's another shot down the road but man the lack of quality in those Custom Pro's left a bad taste in my mouth.
