PLII calls for Wide Grip BP. My grip is already maxed out at comp standards

I bench with my pointer finger on the rings. Do I sub for another variation or do I go wider, and if so, by how much?

I’d do close grip bench in this situation.

What are your thoughts on duffalo bar? Or would you still recommend CGB?

I’d recommend close grip over benching with a duffalo bar.

How close is a close grip on the BBM templates?

Closer that your standard grip and for many people this works out to index fingers at or near the knurling.
