Hi There,
I am fairly new to the dropshot scene as well, have fished Touws River and was beaten to bits, but no takes. There was "Springers" jumping all over. They took the small "no name brand" soft bait fish rigged on 1/4 ounce jigg, but on the tail, bucktail worked the same outcome.
Will be trying a no.2 longshank right to the back with sliding bullet weight for casting.
I have had the same result as above in the Kaaimans river and Great Brak River.
Any suggestions?
