What tonearm will better mine?


I have been running a 12" Jelco SA750L with an upgraded Decca Super Gold on a Garrard 401 for a few years. I'm happy with the sound and happy with my pre, power and speakers. (Croft 25R, EICO HF35s, -good tubes, Quad 57).
I keep hearing that my tonearm is a weak link even though it sounds pretty awesome to me. What would it take to replace the Jelco and make a significant improvement? What should I expect to hear better? Would I have to drill the massive plinth? Thanks.

Which of the arms mentioned have on-the-fly or at least easily repeatable VTA? I am surprised to see many tonearms that are raved about don't have easily repeatable VTA and I wonder if their owners don't adjust VTA for each LP or what? I know Pete Riggle sells adapters for Regas and a few others, but do you guys not adjust VTA with some of these arms? Thanks.
Cheers,

@binkt Please tell us more about your experience with the Pete Riggle Woody. I just read up on that arm which I have not heard, and it has many amazing features that I haven't seen before like on the fly azimuth adjustment. (Not sure if I am brave enough to do that). 
I also believe there is a version of that arm made specifically for use with SPU carts. 
Anybody else hear or own these? At $1900 including multiple headshells and weights for low/med/high compliance carts, it looks like a good value proposition, at least on paper. Cheers,
