As others have said, I was really disappointed with the NRX 822s SYR (I just didn't find this any more sensitive than my GLX Shakeyhead Rod). However, with how unimpressed I was with the SYR, I was extremely impressed with the NRX 822s DSR. With that being said, all I have ever used my NRX 822s DSR is drop shotting and I have used weights from 1/8oz up to 3/4oz. With the tip on this rod, it easily fishes those lightweights and with the strong butt section of this rod, the 3/4oz. maybe pushing it, but you can still use it. With the question you posed (as far using it for drop shotting, shakeyhead, and lightweight tubes), I would seriously consider the NRX 852s JWR. If I can only bring one spinning rod with me that can cover a lot of techniques, it would be this one. For as much as I love the DSR, I just don't think that tip is stout enough for shakeyheads and tubes (even though I do think it has enough backbone for those techniques). Now if you add a second NRX to the line-up, get the DSR and just have it dedicated to drop shot as your 852s JWR could handle the shakeyhead, tube, senko, light T-Rig, soft jerkbait, etc. duties.
Good luck in your search and in the end, any NRX will be the right choice (except maybe the 822s SYR).
