Preferred pulley setup for daily driven car?
Been around for a while; once upon a time had an ASP crank pulley on, took it off and then was stock for a while. Now I'm looking to add some more power but looks like the pulley landscape has changed a lot: clutched pulleys, fixed pulleys, and now VRP with their modular balancer combo.
My car is my commuter and gets driven about 60-70 miles daily, I am not looking for any compromises in drivability or comfort. Taking out any variables such as labor, and cost, what is the current preferred method to adding reliable power via a pulley?
I guess really I'm trying to understand if there are benefits to a SC pulley VS a crank pulley at this point. I could go either way but don't fully understand the pros and cons of either setup. Thanks in advance for any help/advice.

Personally, I'd never touch the crank pulley - but that's me. Tons of people have done it for thousands of miles with no issues. I would never do it to my car, the potential of damage is far greater than if something happens to your blower pulley.
Throw an 83mm upper pulley on there with box tune (tune of your choice, they're all tried and work). It's the perfect daily driver setup with zero compromises and good bit of power/TQ bump.
For what it's worth, I daily drive my car and rarely drive it like a granny.

2nd on not touching the crank pulley. It's not just a pulley, it's a harmonic balancer.
I've done 70k miles on a 72mm upper and stock lower and it's fine... except it eats oil 1qt every 1k miles.

The vrp kit uses an innovators west harmonic balancer. It's just a standard pulley, does this change your stance?

If there would be an ATI Super Damper then I would've invested in that. I know that someone over here has one, which was custom made. I had one on my Mini Cooper S and was highly impressed with it
It was 2% bigger and a even bit lighter than the stock rubber unit.

I would be fine, but I don't know the benefits of replacing lower pulley over upper pulley if they achieve the same results? Upper pulley is a 10 minute job if you have the right tools. Crank pulley is a much more involved job; is it worth it?

Personally I use a stock lower pulley and the oem upper pulley, which I had milled down from 91mm diameter to 88mm. So original build quality and oem nachi bearing and about 0.1 bar more boost. With supporting mods I have about 100hp more than stock (cams, headers and 80mm throttle body)

ASP crank 195 here since 2013 and 30k miles and I have it pinned for extra piece of mind.
crank will give you less belt slip as you increase the surface contact area of the belt. A smaller upper course is less to grip so more belt slip. BWK will help but likely to still get some. I still run a BWK with my 195 to ensure still lower chance.

I've ran various sized upper pulleys on all three V8Komp cars I've owned and not one slipped to be noticeable having the belt wrap on it. Held boost steady all the way to shift. If there is/was any slippage whatsoever, it would be negligible.

Is there a noticeable difference between stock and an 83mm and tune?

83mm pulley is a good pulley i tried one out after having the stock pulley for all these years, i had the griptec coating on mine. the car makes 537-533 hp and 570 torque that is with several deg of timing less then my stock pulley tune. on a 35mph to 130mph pull lugging it in 3rd gear to check air fuel on street only a 38 deg rise in air charge temp. Race fuel over 600ft pounds of torque. pretty sure if i wanted to dip into the 10s with the 83 i can considering the stock pulley times. unless your getting the proper cooling and recovery 83mm pulley works just fine all around.
