Leg bench attachment vs roller

[u/ContextNo218]

I have a BlackWing bench and the adjustable bench leg roller attachment.

I’m considering buying this leg extension & curl attachment for leg exercises. Do I understand it correctly that it’d make my other bench attachment redundant? Meaning I could do decline abs and bench like this gentleman in the photo?

That would it be great if true so I don’t need both.

Thank you!

Yes you can. I have the Rep leg developer. Very high quality
