I like buying once. You can always slow it down if you want.
It’s not always easy to just swap in new pistons.
As a disclaimer, I always run as much compression as I get get for the fuel I use. Always. Up to about 14:1, with the correct fuel there is no downside to CR.
The tune up window gets tighter but they run cleaner and make more low and midrange torque, which is a big deal, especially when you have more than one gear change.
I just wanted you to know that, because I always advocate for CR. So I am very biased about it.
