Are those clousers or crappie candy or both? Whatever they are, I like them. Look very good, maybe a little bulky for my tastre but that is just me. As for going deep, I don't see why they still wouldn't work on a sinking a tip or intermediate sinking line. I fish 30-50 foot deep pools for salmon in the fall and have no problme getting down to the fish with just a sinking leader and sinking tip. It does get a little boring waiting for the fly to sink that deep but if that is what it takes.
I love taking my kids fishing, now if I could just manage to fish at the same time.
