Yea, and they aren't as expesive as some of them. I just can't see paying 3 or 4 dollars for one football jig. Like you I lose my fair share which is why I am now looking into pouring and tying my own. Seems like once you pay for the inital supplies and tools it cost way less to make your own versus buying them..
I like the brown craw but just found out it is being discountinued, another good reason to start tying my own. I may have to look into the heads you are talking about, all I am concerned about is getting a good hook set and having a jig that doesn't hang up as much. So maybe the 60 degree striaght eyelet would be as good. I fish mine on 15lb P-line flurorclear most of the time.
