Using braid with longer fluorocarbon leaders will be fine. Once the water warms up and the fleas appear, the braid will load up with fleas and be unusable. Adding approx. 150 ft. of #30 lb. Big Game mono to the braid will help with fleas during summer months. I have gone a different route, spooling all my reels with #30lb. mono, then changing leaders to meet the season and conditions. #15 flouro. for browns, #20lb. for kings, no leader for flashers, dodgers, meat rigs.
