Need some input... is it a no brainer to get a new bike?
I have an REI Ponderosa with Deore DX rerails and hubs, a Ritchey Forcelite handle bar and the standard hard fronk (hard), that comes with Novara bikes.

I guess I ride single track and fireroads only, no serious downhill, and really no serious uphill either

But it looks like I'll gain some control, if I got the new Ponderosa, rather than try and swap out parts. See, i'm no wrench when it comes to bikes. Trying to dial in a derail for me is like trying program mainframes when you've been selling furniture you're whole life. It ain't going to happen.
So there's labor.
new Pondo's have Dart 2 shocks, disc brakes, and a 20% off coupon if I buy it this week.
full write up from their site...
AN6 construction, high-end SRAM drivetrain and aggressive geometry make our Novara Ponderosa the first choice for no-holds-barred XC performance!
AN6 aluminum frame is double-butted (thick at the ends, narrow toward the middle) for a significant savings in weight without a reduction in strength
Double-butting also improves ride quality and comfort by reducing high-frequency vibrations traveling up the frame
Hydoformed downtube is lightweight yet strong, providing critical vertical strength at headset and horizontal strength at bottom bracket
Pondo's long top tube reduces the likelihood of wheelies during aggressive ascents; the long wheelbase adds stability and confidence to descents
RockShox Dart 2 fork meets changing needs; run it plush (100mm travel) to buffer unyielding single track or lock it down for a stiff, efficient ride
SRAM drivetrain is all performance, featuring the deluxe X-9 rear derailleur and snappy X-7 shifters and front derailleur
Twenty-seven speeds let you handle any terrain as you want, whether you're romping hills, cruising easy or making serious speed across the flats
Two-piece Truvativ Firex 3.1 crankset is strong, lightweight and easily maintained
Avid BB7 disc brakes and Speed Dial 7 levers provide sure stopping power and controlled deceleration no matter the terrain or weather conditions
Lightweight WTB SpeedDisc rims feature I-beam double-wall construction for strength and durability; WTB Raijin tires provide tenacious traction
Truvativ XR Riserbar and stem provide excellent steering control and comfortable positioning for off-road terrain
Anatomically designed, the lightweight WTB Pure V Comp saddle offers exceptional comfort and support from a streamlined platform
Just get on and ride, no fancy shoes required—alloy platform pedals accommodate a variety of casual shoes
I figure I'll ride more if my elbows don't hurt. Mostly I just want to run the Rock Creek ride from like Mammoth ski resort down to Rovana. I like shuttle rides. It's like kayaking for your bike.
