It's not the best of setups for jig fishing, especially if you are using a jig with a weed guard.
While spinning setups certainly work for jig fishing; most on here will tell you that a heavier jig with a trailer (like what you're using) is baitcaster territory.
To pull the hook through the fish you will need a stronger line with less stretch. I prefer to use straight 50 lb braid for murky and stained water or 50 lb braid with a 12-14 lb fluoro leader for clear water. Again, that is with a baitcast reel.
Is your current setup keeping you from getting bites? Probably not, but if you do get one it wil make it more difficult to land the fish.
