Even with the pressed process, its pretty damn rare to have crank problems, I think people spend a lot of money trying to prevent/fix problems that would never occur.
IDK-i have understood most are 0.010 out!
That is a lot of wobble.
That is why TC run a chain to the cams and not gears right?
There is no QC there.
Back to the comp / sprocket- I say do it.
I just don't see how a double wheel crank is going to shear from feeling a little more of the pulse.
like I said-if it does it was going to anyway, just latter.
Was the guy an actual mechanic or the usual parts swapper that passes for a mechanic today? There is a difference and if you understood the physics behind what a compensator does, the ratio's involved and the lame crank's harley uses it wouldn't be a point of contention. A solid comp sprocket is going to hammer the crank and trans bearings, it's when something will fail not if . All depends on the rider, the bike and riding style.
Funny thing is when the gearing ratio was lower in the primaries you never heard of a comp going bad, get your head around that........
Shop with a good reputation who also builds engines and custom bikes. I specifically asked about scissoring the crank and he said of all the ones they done it's never been an issue and he's never even heard of anyone having that issue. Said they installed a ton of them, so I gave them the green light.

Good luck then honestly, I've personally lunched a few cranks and changed more than a few belonging to others. Maybe I'm overly **** about my builds verse todays slap & go guys.

Mine where too much happy hand, usually the belt would let go but on 2 occasions it didn't and the output shaft either spun in the wheel or snapped off at the bearing. Others various reasons but everyone was scissored to some degree, you look at the overall build, condition of the bike in general and a bit of chat the owners you can usually sort out what went down. I am not a fan of the machine assembled pressed together flywheels the twinkies and later are using.
My compensator just failed at 50,000 miles on my 07. Been looking at baker and HD replacements. I measured my crankshaft runout when I put in my cams. 4 thou. Better than most but worse than the evos. Hadn't considered the solid sprocket til now. 2500 ft/lbs to scissor the stock crank in the s&s demo. I think I'll try it. If it scissors I'll go with s&s flywheels. Thanks for the tip
Myself and a few local friends have found a cure for most of the compensator problems that we have experienced ( Ultra's and Road Kings). On the newest version that spins the oil ( 42200064A) we have been polishing the contact surfaces , ramps and spokes to stop the wear and self-destructiveness . Myself and others have over 50,000 miles on them , no more metal particles in the oil and at 45,000 miles there was zero visible wear , no slop in the springs and no rattle or noise while running. Most of us also pull trailers and have stage 3, can't say it solved the problem altogether or forever but we are more than happy with our results .
