Back in the fairest cape... with crap wx

Arrived at the field with my little blue license fresh from the CAA to drain the rotten feul from the tank to be informed that while i was away 7 kittens had been born on the back seat... still not sure how to take this. But atleast someone washed the seat covers

So DNP now has atleast 7 lives and has been nicknamed the "kittyhawk"

Took her up for the first flight, with instructor for ballast, and she flys like a beauty... wing is abit stiff though. Can I fix this by loosening the tension on the wing? (increasing billow shift?) It is currently set in the midway position. Something that is annoying me is that with a heavy pax the bar is almost against (about 20cm back from) the profile tube in the neutral position... Inst recons that we may been to move the hangpoint... I want to go solo with her to see first.
Any suggestions
