Need help selecting spindles 84 C10

[D13]

Plan is to upgrade the suspension for a summer driver, probably close to 20 000 miles a year. Intent is moderate drop, axle flip in rear, rebuild front with lower arm caster mod, HD Moog coils trimmed either 1/2 coil (if under the 6.2 diesel) or 1 coil (if under the inline 250). I run close to stock tire sizes, fond of Rally rims, not into 20's or low aspect tires (rocks and potholes are harsh on that type of stuff). I drive 5 miles dirt, 10 miles city, 25 miles highway, and 30 miles paved county roads of decent quality every day. Potholes in dirt and city make big drops impractical, and I'm not interested in air ride. Given all that:

I'd like to use a 2.5" drop spindle, and just bolt on my existing hardware and go. Where I get confused is the selection and quality reports. All of these are in the $240-$280 range except as noted
I've heard a lot of iffy reports on DJM so took them off the list. .
Ground Force 6001's - about $70 more than others, no particular reason given
Classic performance CP4S4
Classic performance CP30106-4 appear to have less drop but claim to have greater fender clearance, are modular, and have adjustable steering stops
Summit SUM-G703 - Chrome moly spindles
Western Chassis 13200 - appears to be an older design
ECE #911-7387HD

Any guidence, any of thise have improved geometry, or anything else I should be aware of?
