Well as far as drift fishing goes, go with the IMX. I think they are the lightes most sensitive rods there are. But if you don't need the feel, go with the something else. My dad and I both have G-Loomis's for drift fishing and boondocking, but I wouldn't spend the money on an IMX or GLX if your not drift fishing. The lamiglass's are beautiful rods, but in my opinion for drift fishing they don't have the feel of a high end loomis. My dad has 4 lami's for steelhead and we leave them home when drift fishing. I have never used the Rain Shadow, but my next steelhead rod will be a IMX 1082 or 1084.
