21p Laser 2 here-with my 19p Laser 2 I lose nearly 5 knots, but it could do with reprofileing. Top speed is at around 5350 rpm The boat leaps onto the plane very quickly with either prop, so I'll stick with the 21p.

Apparently the trick with keeping Opti oil consumption down is not to make massive changes in throttle setting as they use an awful lot of oil under hard acceleration. I tried it and it makes a bit of a difference when I don't slow down

Only real gripes are the price of spark plugs and how bloody awkward they are to change.
I buy 12 (3 packs of4) or multiples at a time from
RockAuto Parts Catalog

or
NGK IZFR5G stock# 5887 - Speed & Custom Marine

Even with shipping (request USPS as much cheaper than UPS/FedEx) they work out much better - and I can afford to change regularly. Search with part no 5887

They are much easier to change on my later 2007 model than my old 2004 - different injector rails. I always use a piece of fuel hose as an extension to my fingers which makes it easier and no risk of x threading

Thats about what I paid for mine via ebay, but it's a pain if you don't already have them (got caught once!).

My injector rails are coming off at some point soon so I'll change the next set then
