What size prop R U running

I have a 20 ft with a 250 opti racing with a 12 inch jack plate. WOT im at 5500 rpm and 72 mph, I know that my boat should be performing better so I was curious what prop any of you were running on simular blazers.

I have a friend that runs a 27p and it flies!  Have no clue what brand, but I do know it was worked as soon as he got it, before it was put on the boat.  He said it needed cupping for the hole shot?  Ain't got a clue

Just to recap, I found a 28 pitch bravo1 that had 1 inch holes, I got a much better hole shot than I did with the 26 TXP turbo. plus I gained 6MPH. At WOT its running 78 MPH @ 5800 RPM loaded with full tanks and a passenger. From what I have read I could get another 5 MPH by getting the hub shortened and getting it cupped. That will have to wait till another day though. The boat handles better as well in the mid range.
I wound up 1/2 inch below the bottom.
