I built 6399U W/O flaps and after 4 yrs of floating indefinitely decided to go with the belly board. If you fly final at 70 and then pull it to full deflection you will hit the corn unless you add some power. The biggest issue as I see it is that when you really start slowing the KR down you ( at least in my case ) must go to a nose high attitude which can be an issue if you are not familiar with the runway etc. Make no mistake-------------a properly sized board will claw the KR to the ground, Last week I went in to a 1800 ft turf strip that I never in a million yrs could have done w/o the belly board. YOUR RESULTS MAY VARY.
