Im making a trip to the mighty mask mid september anyone got any ideas on the best team of flies to use,hook size etc....???

I would think that you have 2 options.

The dries in which case it would be small sedge patterns and daddies in or around the shallows or out in the deeps pulling the wets where a Gorgeous George, Melvin Octopus, jazzed up Green Peters, Claret Bumble, Dabblers is what you would need.

There is no real secrets for Mask its just a case of picking the right spot.....a big lake and all that.....

I hope you have a good trip
