Fordound is a pipe storage yard and has been for quite a few years.
Hatton is a private strip available by PPR only (and the Flying Farmers!).
Insch is a nice spot but as noted not ideal in either of you chosen machines.
Longside is a possiblity - although quite a drive.
Whiterashes is possible but again can be pretty soggy so a good briefing and PPR are essential.
