Just Got a NEw Traxxas Rustler

It's an xl-5. I have been into the hobby for 6 months, and have a Trinity Monster Horsepower 27t motor, 2 team orion super duty packs (both only 2400 mah). I also have the red rear springs, waterproofed receiver/ servo, wheelie bar, fiberglass shock tower/tie bar, stocker back tires, and some Anacondas. I also have some old but fairly new traxxas protrax tires. I'm thinking I'll either get dirt hawgs, or geolander. I am saving up for a sidewinder or a VXL. Which do you reccomend? What are some good combos? I need it to be as cheap as possible, but I want a good motor. I don't need to go 70 mph, so I don't think I'll ever go lipo, but how would a tenergy 8 cell pack do on a brushless setup? I'm also in the process of getting some new tool and ble RPM a-arms (front and rear), and ble aluminum castors. For rims for the new tires I'm going traxxas 2.2. For sand I'm getting sand paws, and I already have an RPM bumper. I'll also be getting steel transmission gear.
