It's the lesser of two evils IMO.
A 2618 piston has always been the gold standard for strength and endurance in a hi perf build. No premium piston builder would recommend something different if you went to them and told them that you were gonna put a forced induction power adder on top.
But, I think they are expecting you to make tuning errors,..I think they expect you'll have a part failure that'll cause a lean condition,...I think they expect you'll prefer a melted hole in your piston to a shattered or broken one that is waiting to get jammed into the head the next instant that con rod tries to shove the whole mess back up in the normal course of rotation....
But,..that's just me..I really don't know what they are thinking.
Every freakin engine I've built ( save 1) has had a true forged piston in it..The noise, the excessive skirt clearance required, the potential cylinder wear, and degraded ring seal that come as a result are the compromises that usually " weigh out" in favor of the 2618 piston in the end.
But don't take my word for it...call somebody.
I use Racetec Pistons in the monster..call them...ask for Randy.
And I wouldn't balance my own engine either..you need a rod scale that balances the rod and checks both ends of the rod
