i have never fished with a loomis rod but i did just purchase a Berkley lighting rod 7' MF for under $40 and it is by far the most sensitive rod i've fished with. spooled with 20# power pro i can feel the difference in mud bottom or gravel in 35 fow with a 3/8 0z jig. i dont know about the ultra light or light rods but would think they would be just as sensitive in fast action.
