Pioneer Balancer

I Love My Ty's
I have been looking at several Pioneer balancers. I'm just not sure which one to purchase.

After searching through posts I found were a member used balancer part# 872021. But I was wanting to try a balancer that had a larger diameter.

Of the 3 I am looking at part# 872021 and 872022 have a note stating: Top dead center (TDC) mark is located 10 degrees from the keyway. While 872023 the note say: Top dead center (TDC) mark is located 13 degrees from the keyway. Is the TDC mark 10 or 13 degrees from the keyway on our stock balancer? Or could either the 10 or 13 degree be used and the timing pointer be adjusted to TDC? Thanks in advance.

Here are links to the 3 balancers.
