DTs are my favorite crankbait. i caught the fish in my avatar on a DT-4 sure-set. very durable and very nice action. i have used all the styles of the DT (regular, flat, fat, sureset) and never had a lip break off. from what ive read though, the lips only broke off on the older ones, and the deeper they dove the more easily they broke (because of the longer, more fragile bill). but they have fixed that problem since and the newer models of DT are very duarble. well reccomended.
good luck with your new crankbaits!
