Wiseco oversized pistion in Inline 6

[Jim662]

I read in older posts to stay away from Wiseco pistons. My machine shop guy ordered me a .015 over pistion from (I believe) Wiseco, PN 9015. The weight seems heavier than the other pistons, but I'll check it on a scale later.

What are the reasons (if any) to avoid Wiseco pistons? Should I have him take it back and get the Sierra piston?

Thanks.
