I saw where do-it molds was making a flat bottomed football mold for 2013,it is designed for the trokar hooks,which are very expensive. I forgot if it was a weedless design or a screw lock,I beleive it was a screw lock. Most of there 2013 new molds are for trokar hooks,not saying that there won't be another hook that will work also,I feel like they will accomadate several defferent hooks. Like most other molds.
I'm perfectly happy with the regular football jigs myself,but different strokes for different folks.
