Actually I was thinking about haveing one firing arc on saucer just like on SNS Galaxy, It would be very powerful, short burst, quick recharge, tho I may consider makeing phasers the way I made them in post nemesis enterprise-e, medium strenght, very short bursts and very fast recharge rate + multifire (this would be very similiar to the way phasers fired in Nemesis.
As for torpedos, ship will be equiped with standard nem style quantums, I don't think about placing torpedo turret or any other special gun which will rip enemu apart with one single shot ;) so don't worry this ain't gonna be "god ship"
There will be 4 tubes, 2 fore and 2 aft, forward tubes will fire 3 torps each and aft will fire 2 each.
Back to phasers I planned to have one single dorsal and ventral galaxy class style phaser arrays, two small strips on the aft dorsal saucer. On the secondary hull : one ventral array, one small phaser strip on the side of both pylons + sovereign style pylons phasers top & bottom.
