Mike: The L1-BK has the new scalloped head.
nekomane: The case came with 'pick-n-pluck' foam (Semi-pre-cut into squares). Basically lay everything out. Then I cut the foam using a playing card or business card. Once the piece is out, I used a knife to cut the piece to the right height and put it back in. It's really easy to use, but take your time.
