#44 looks cool, it just doesn't seem to symbolize an L, P, or embody customization at all. #43 Looks the best so far, very creative, very slick and classy. It's a bit hard to make out when it's smaller though.
I still like #46 better because it feels more solid. It's still looking like a maze puzzle to me which is a bit too busy for my taste. The elegance and class is there though.
#47 is just too skinny, wispy, and girly for my taste. I want something that's more solid like a brick, not light and airy like a feather.
