So I have not read extensively on burst,
Can anyone tell me if burst mining is worth getting into as of today?
A large portion of the PoC rewards have already been mined. That said: yes, it is
for sure worth mining today, as Burst mining requires trivial amounts of electricity. Feel free to join us at

Currently plotting 3.5 TB for burst, any recommendations?
I recommend Blago's XPlotter for plotting. It creates optimized plots in one go (back in the day, generating plots and then "optimizing" them was a 2-step, sequential process). I also use his miner for my 40tb, and works well for me. Also, look for a pool that doesn't have a maximum deadline if 3.5 tb is your total space.
I currently have the plotter built into the wallet working, would you say to continue with this or to cancel and move to blago's xplotter and again would the miner utilized in the standard wallet be effective or also worth switching to his miner? What does your 40tb setup consist of and could you link me to your workers?
If you mean the Windows wallet from "daWallet", then you're in luck because XPlotter is the plotter used in that wallet. For mining, I think the windows wallet uses jminer, which is another good choice. If you're happy with it, then I'd suggest to keep using it. Take a look at the workers at
http://burst.ninja/. Not much info you can learn from looking at "workers". Burst mining in general is pretty straight-forward though: plot, then mine. There's very little you can do to in terms of configuring or tweaking to get better results (like in typical gpu mining).
