Versatility is really the key here.
Shallow water conditions don't give you as much room for error as normal winter conditions would. You still need to be fishing the bottom, but most shooting head type systems are too heavy. Many varieties of sinking lines will work, but our top recommendations go to the RIO VersiTip and the 250 gr. Mastery Wet Tip Express. The Wet Tip Express line handles better, but the VersiTip gives you greater versatility.
