They are good cranks.  I have caught a fair share of fish on the DT series too.  

But, just like any lure,  different brands have different places.  

Floaters vs suspending, wood vs plastic, wide wobble vs tight wobble....etc.........

You really have to play around with the different brands to get a feel for what works best and when.  

DTs are nice cranks.  I bought about 16 of them for $3 each, which was a really sweet deal.    

I've heard plenty about LCs, but it'll suck to have to loose it due to a snagthat's if you don't have some type of lure retriever.
