To get more out of your practice put up your largest SLK on a similar line length to what you are using
for your Rev, then try for-mating on it form the top, bottom and sides both leading edge first and
trailing edge first.
If you fly your Rev in front of your SLK you can take the wind out of its sail making it collapse,
move your Rev away and it should recover.
If nothing else it gives you something different to try.
