I have 3 Loomis rods 2 7' HM IMX rods that I use for jigs and worms and 1 8' GL2 heavy rod that I use for flipping. All of these rods are spiral wrapped and are excellent.

Currently I am building 3 American Tackle rods. They are lighter and I was told that they are more sensitive. I will let you know when I get a little on the water experimentation.
I don't think there is that much difference between Loomis and Shimano now that they bought Loomis out.

I did hear that Gary Loomis is starting his own line of rods again real soon. How much truth there is to that I don't know. I hope this helps. Ryan
