What RPM are you seeing with the 23 3 blades? Are they mirage, or Mirage plus?
If you need a tad more RPM at WOT, i'd try a 21p Revolution 4 blade. If you're rpms are good, or maybe need a tad less, I'd try a 23p Revolution 4 blade.
I think you would be happy with a switch to Mirage plus 3 blade props
The Laser props are designed for small light boats and are likely to have high slip numbers on a large heavy boat.
