I use the TRDs with that classic flat ned head shape all the time, either 1/10 or 1/8.
I think you get fewer snags by throwing directly into current. As you start to get sideways into current, my theory is that you start to get more bow in the line than can basically get threaded into rocks. So I try to position myself directly downstream from the area I want to pitch the ned to, if I can.
It depends on the rock bottom type too. There are some areas where no matter what you do, you’re gonna get hung up. But those ned heads slide over smoother rock bottoms a lot better than you might think.
There’s also some subtle stuff you can do when working the bait. If it’s a super snaggy bottom then you can kind of skip it across the bottom a little quicker as opposed to straight slow dragging it. I usually try to do that when I’m casting more perpendicular to the current. After you spend some time throwing them you start to get a feel for how much bottom contact you can get away with before you end up in snag city.
You still get hung up though. When you’re wading or in a kayak, you can usually wade or paddle over and just pop it free.
