I recently did the istirdye (Shall shells) in Nashmau using a robber rig. The bit rate was absolutely stunning. They were exactly like shall shells. 90% of the ones you pull up will be them. 5% will be the losters and another 5% on rusty items. I managed to get an entire lvl within 45min. of fishing there. That may have been luck based, but them biting as much as they did was shocking at the most. I used a Hal. rod and robber rig.
