For microlights and VLA's you should try Newton Peverill. A very friendly set up but a difficult approach onto the westerly runway with power lines right on the threshold.
Compton Abbas is great but I understand that their landing fees are not particularly sympathetic towards microlights.
PM me if you want some friendly contact details for Newton Peverill.
Incidentally, I live just north of Poole and it takes me 25 minutes to Compton Abbas.
