Crank hub drill difficulty/Pin fatigue

[Spaceturtle]

I've been on the fence about swapping out my stock hub for an aftermarket. Right now if I were to get it done I'd probably lean towards one of the 4 pin options. I know precision design has a keyed version which is said to be easier to drill for. Anyone have any idea how difficult it is to drill for the 4 pins? I can't imagine there's wide spread installation issues and I think I've only seen one thread about a really bad drill job. Any first hand bad experiences? Also, has anyone looked into strength/fatigue testing on the pins of this type of hub? Maybe there's a engineer or two on here with some opinions?

When it comes to these hubs, you want to go with the following.
1. Go with reputable brand.
2. Go with a hub that’s symmetrical as an unbalanced hub will vibrate at high speeds causing crankshaft and damper to shake, not good.
3. Less pieces the better. Meaning 1 piece hub.
4. Go with a reputable shop. Do your homework. Get the job right the first time.
5. Don’t cheap out.

With a quality jig the worst thing I could see happening is a broken bit.

I had a 1 piece 2 pin and it was rated to 1200+ hp. More than double my output.

The shop that installed it took no joke about 2 minutes to drill it so not sure how much easier it can get.
