in regard to the head, it was bullet shaped on the originals...however, James eventually went to the round head and it worked just as well. I have several hundred that will probably never see the water. I've fished the no alibis for forty years and I believe their effectiveness was due to the short/small profile. Livescope has proven to me that smaller bait profiles will work when the fish are lethargic and won't hit normal profile baits. That's why in the summertime, the scopers will downsize to 1/64 or even 1/80 jig heads using hand ties or a small 1.2" plastic. And that's why i have shortened the tail on my hand ties.....sometimes less is more. just my .02
