I use that head and I love it, I have pictures but can't seem to upload anything since photobucket crapped on us. Anyway, I find that head to use a hook that is plenty heavy but if you want heavier look at the Trokar Pro Swim Jig, it uses a stout flat eye hook, the 32796 or the EC 2706. I wasn't sure if I'd like that head with a flat eye hook but I actually love it, that is the swim jig I use for heavy cover and for bladed swim jigs. Now, the casting jig head you are talking about, Muskygary is correct, Barlow's has a heavy wire VMC 7217 30 degree hook and a Mustad 32850 30 degree hook, both of those hooks are slightly heavier than the Owner 5317 which is a 60 degree hook. I do not know what size head you plan on using but I'll give you some help. You can modify the casting jig mold to accept the heavier hook, it isn't hard but if you do that I wouldn't change the hook size. What I mean is that the small size mold I would not use the heavier hook on any cavity but the 1/4oz and I wouldn't use over a 3/0 on it. On the large size mold, the 5/16oz, 3/8oz and 1/2oz I would not go over a 4/0 unless you are an experienced lead caster. The reason why is the collar of that mold will work with the heavier hook when you modify the mold but the clearance will be tight enough to give you some trouble with the lead not forming the collar fully. I know this because I modified that mold for the 1/4oz to take a 5/0 32886, the mold uses that hook but only in a 3/0 and 4/0 and in order to get the mold to pour right with the 5/0 I have to increase my lead temp and make sure my mold is really hot, like really, really hot in order for it to fill out. Good luck.
