Since @rippin-lips is such a negative influence on me, I now have an SV103 that is currently rod-less so I'm considering treating myself to my first Loomis.  Loomis seems to rate their rods differently than the Dobyns, Kistler and Daiwa rods I have so wanted to get the advice of those here.

 

In all likelihood, this combo would get the most use with weightless senkos, 1/4 oz and less Texas/Mojo/Rage rigs/jigs and other feel techniques.  The cover being fished would run the spectrum from open water, rocky bottom, light grass and around (but not in) stumps.  I'd need to stick to the 80x, 84x or 85x models due to rod-locker length restrictions.

 

The floor is yours....

Depends if you want fast or extra fast action. I've handled a few of the 2016 GLX's and I'd say their tapers are 'true'. I own the 853 JWR and have limited use with it due to the weather, but I've used it for 3/8oz jigs and I think it's great. I only plan to use it to fish jigs and trigs from 1/4oz to 1/2oz plus plastics. I think for weightless senko's and 1/4oz and less rigs, plus the cover you described you will be fishing, I'd go with the 2 power rods. Personally, I like length so I'd go with the 842 MBR with the fast action for more versatility. But, I'd get the 852 JWR with the extra fast action if you plan on only using it for the applications you described.

 

I plan on adding a 842 or 843 MBR soon, possibly the 842 as I just broke a 6'10" medium power fast action rod.
