I've chosen
Tipton Carbon rods. (ETA: this is not the one I have; but it's my next one...)
My key concern with rods is intrabore flex and bore land dragging caused by metallic rods taking a set or a bend.
As far as I can tell, the carbon rods don't do that; and in my experience, every metallic rod I ever had eventually did.
If you can roll yours on a smooth tabletop and it rolls smooth, you're good. Anything else, and you're not.
The max force design appears to employ a spring clutch component, something I became familiar with when I was an IBM Electric Typewriter Repairman (Office Product Customer Engineer) in the 1970's. The spring clutch was the core operating element of the
IBM Selectric Model 71 (golf ball head) typewriter. It worked without gouging into the drive shaft.
Recognize the voice of HAL? (close enough, anyway) If you transpose the HAL acronym letters to the next alphabetical ones, HAL becomes IBM.
After fixing electric typewriters for a living in my early 20's, firearms seem like very much simpler mechanisms.
As an OPCE, the biggest peril was horny secretaries. Most of us wore wedding rings as a preemptive. When you held down a driving territory and got upwards of 15-25 calls a day plus a quarterly PM schedule on all the machines in it; you valued your time above all else. My territory included Northwestern Newark NJ, and sizeable chunk of East Orange. I was the first OPCE IBM ever hired who came without a college degree. Closest thing I ever got to a college degree was a USAFI College equivalency proficiency.
The second biggest peril was the Trichloroethane cleaning solvent. My Brother was also an OPCE who started earlier than I.
An electric typewriter repairman was part grease monkey, part physicist, part electrician, and part diplomat. We did this wearing white shirts, suits, and ties; and washed hands both before and after using the urinal.
We both had the exact same medical issues decades later, and were also both heavily exposed to AO; him at McClellan, me in SE Asia. Congress is still dragging its feet over approving McClellan Vets as eligible for AO VA Benefits. Won't help him when they do; it was a Covid comorbidity that helped kill him, and my way will likely resemble his. At least he ducked the cancers.
Huzzah!
