Question on piston and rod balancing

**** me right? Thanks for all the feed back..except for that lumberjack talking about swinging hammers. Since I'll be bringing it in for a balance...anything else I should know or have done while it's apart?
The lumberjack is a pretty good dude once you get to know him lol I don't know the math either other then saying an 800g piston weighs a metric **** ton when changing directions at 3500 rpm.
