Radwagon Derailleur system upgrade suggestions

[Barkme Wolf]

I want to upgrade the shifting system on my Radwagon. Any advice would be nice-
Although I am usually dirt poor, I have a few dollars to put into the bike. I am getting a Thudbuster seatpost and a Diamond Back pillow top saddle. Looking into changing out the handle bars as well.
Most importantly I want to upgrade my shifters because I can't use all my gears and I have nothing but hills on my commute.

That's the derailleur I used to upgrade.

Once you upgrade the derailleur, the OE shifters will work perfectly, and you won't gain anything by changing them.
Replacing the OE cables with Jagwire mountain pro cables will also make a noticeable improvement.

I replaced the handlebars with Soma swallow bars, and they are a real improvement. I did need to replace the brake and shift cables as I have the stem set at max elevation, and the OE cables were a little on the short side, but the Jagwire cables improve shifting, and braking so it was worth it.
