Invector plus and Federal Tss

[jrinny]

I am looking for any advice in choke selection in an invector plus 12ga — shooting 3.5 inch and/or 3 inch Federal TSS 9's. I have shot some through a few chokes I currently have (690, 675, 670) but looks like I should go tighter. Any suggestions or experience with the Federals is appreciated

 Jeb's .655 is producing very good patterns for me with Fed TSS...
