To me I feel switching to braid has been the largest factor in terms of increased sensitivity and "feeling" what is going on at the end of the line. With no stretch in the braid, I am looking for a fishing rod with a softer tip and slightly more moderate action than what I used before to help prevent pulling hooks. Setting proper drag has also become more important as well. Lastly, balance is very important as I feel the lighter I can grip my rig, the more I can feel what is going on. Just my $.02
