maybe you should try both. My 10/2 braid, with a 10lb flouro leader will cast a mile, has little stretch, but the down side is wind knots.Sure it may sink slower than flouro, but I always figured, feeding fish are looking up, inactive fish are bottom hugging, and too much trouble to target.Or you can go 15/4 on the braid, and a heavier flouro leader. Braid will last at least three years with moderate use, in the long run is cheaper.But thats only my opionion.
