ok, was reading some stuff but like yalls view and opinions better. looking at the IM and tons, which dictates sensitivity of rod and the weight of rod? I've seen IM 6-10 is there any higher or does it convert to the HM(whatever the cumulus and cumara is) also this may just be personal preference. I was talking to a bps employee about IMs, he said he doesn't really look at IM rating on buzzbaits, spinnerbaits and topwaters. The big reaction baits were bass usually don't tap it. Said he looks for the IM 8 and up on all plastics and jigs. that kinda makes since anyway what are your opinions on this. real opinions, not back in my day stuff... lol

These specs are irrelevant for the most part and have no direct correlation to rod ratings which are completely subjective. Scrim, resins, mandrels, processes, components and layout all affect the finished product. All the IM and Modulus talk is marketing, ignore it. Look for a rod with a light finished weight that pairs well with the reel you'll use. Don't rule out "micro" guide rods especially for jig/plastics etc. Any rod ratings available are totally subjective and unfortunately there are no industry standards. Trial and error along with experienced feedback are the only real gauge you can use.

 

There is a system called "Common Cents" gaining a foothold primarily in fly fishing. The cents refers to a US penny as a weight of measure for power, action resonance etc. The goal is to apply a quantifiable unit of measure in place of subjective term like medium, heavy, slow, fast etc. Some custom rod shops can do the measurements for you but there is no meaningful database yet especially for casting/spinning rods. 

Thanks man, ok I understand it then

agreed. rod ratings are very subjective
