Thanks! I like #2 the most, but I'd like to see a different font that's a little less corporate or Times New Roman looking. Also, a linchpin is more about what's in the center and not the wheel itself. Thanks!
I was just looking at #7 again and realized it's similar to a concept I had where the L is in the middle of the venn and the rest (inchipin) follows from the middle. I hope that makes sense! I'd prefer a much more elegant font and some stylizing of the venn. Interesting - thanks!
