I like the look of the pro-line kit but it does change things and limit you to pro-line going forward due to size differences etc. and it is a little pricey in my opinion - I'd stick with a JANG wide mod myself.
the survey results seem to be pretty well approved other than the pro-line steering which has sparked some debate.
Since you have some radio stuff off the top of my head I'd actually suggest buying a roller rather than a complete car - much easier to get new via ebay in the US than over here in the UK.
My config of choice based on my research and personal preference would be:
STRC Slash 2WD LCG Conversion Kit
RPM Front Skid Plate And Bumper For Traxxas Slash (80952)
RPM Rear Bumper For The Traxxas Slash (81002)
RPM Gearbox Housing and Rear Mounts (73612)
Traxxas 4x4 Driveshaft assembly rear, heavy duty x2 (6852X) Castle HOBBYWING EZRUN WP SC8 Waterproof 120A Brushless ESC
Castle Creations Neu-Castle 1410 3800 kv motor
ST Racing Concepts Aluminum Front Bulkhead (ST2530GM)
RPM Front Shock Tower - E & N-Stampede, E-Rustler & Bandit (80852)
RPM Rear Shock Tower for Traxxas Slash 2WD/Stampede/Rustler/Bandit (80832)
RPM Front & Rear Wishbones (80242/80182)
ST Racing Concepts Aluminum Caster Blocks (ST3632)
RPM Front Bearing Carriers For The Traxxas Slash, E-Rustler, E-Stampede & Bandit (44.4%).
ANZA/ STRC Hingepins
Traxxas Big Bore shocks (hard-anodized & Teflon-coated T6 aluminum) (2662/2660).
Body shell would be something from Proline or a BAJR.
It might help. It might not
