I am considering the purchase of an ASH 25e. One of the concerns is
our operating field. On some days a Nimbus 3t with 25.5 m tips things
can be a little marginal if the ship is at max T/O weight. How does
the ASH 25 compare if flown empty but 2 up?

We are operating off a 'lush' grass field generally behind a 235 hp
Pawnee or a 185 ( I think ) supercub.

The marginal takeoffs are generally behind the supercub on the
occasional days we change take off direction and are faced with an
initial roll uphill with trees at the far threshold.
