I cannot believe you got them to do a side jack! That is so cool! That is one of my biggest hang-ups about LB-100s & SB-1/2s. Not sure why, but top jacks have always bugged me?
I agree about the front mounted jack, I wont say what it looks like with a straight jack going into it, but I do much prefer a side mounted jack with a 90 degree plug going into it. It just looks neater with the cable over the rear strap lock pin from the back.
