Anyone use 'em? I'd love to get some input on 'em.

Which head design works the best in rocky areas?

Fantastic design + Tungsten...I'm in!   They have been on my shopping list for a while now; I need to just pull the trigger and order some.

I found them to be quite "Snag-tastic".  It didn't matter if it hit rock, wood, grass; it was going to try and stay there.  The components are top-notch, however.  They look great, but mine wanted a new home at the bottom of the lake.  I also found that my line showed more wear from abrasion than with a standard football head or the Owner stand-up heads.  One hook bent, again from a snag, and broke during the re-bending process right at the tungsten head.  May be related to the heat involved in pouring the head...  No issue with hook-ups.  Nice sharp hooks are used.  I did think they were a bit high on the price versus the competition.

That was my experience with a pack.  Your mileage may vary, and I don't want to tell you not to use them.  They may work for you.  Tight lines.
