You only need to find 9 to 10 G from the heavy ones.

Working the areas I recommended won't reduce strength, just be sure not to leave any sharp internal corners as this leads to cracking.

Got an old piston to practice on?

Before cutting, you could always mark the piston and post a pic to make sure we are talking about the same areas.
