Has anyone had the opportunity to try the same model of G.Loomis rod in both GL3 and IMX? Is IMX worth the approximately 25% price premium?

I currently have a GL3 rod for steelhead but am looking for something beefier for trolling / jigging in Commencement Bay and am looking at the HSR1021C. It is available in GL3 and IMX, hence my dilemma.

Any suggestions or advice are appreciated.
