If your gonna troll I'd stay with the GL3.If you were gonna get another steelhead rod I'd go for the IMX for the sensativity.Your not gonna feel it while trolling.Good luck,

P.S. I boondoog out of my sled with both 1141 GL3 and a IMX.I've caught more metal on the GL3 then the IMX,however the IMX just feels better.I have two 1141 GL2's that are boat rod's and there gonna stay that way as I'm not impressed.
