Thanks for the feedback. I love the Rive so far myself, and I also found out that replacing the main slot with a medium ballistic weapon can give it a lot of versatility, especially in big fleet engagements and on AI use.
Here is the loadout I am working with this last day.
The accel shields can both negate the front shield disadvantage and keep the flux low enough to keep the thumper 24/7 on the target.
The accel thrusters augment the shields beautifully for defensive maneuvers, and also can be used to:
1. have the main gun trained on the target while strafing efficiently
2. rotate the ship in a snap into revolver cannon arc radius for missile or fighter protection.
3. prevent flameouts from the salamanders (a big threat for the ship due to its fragile nature and front shield emitter)
Stab shields will give you more bang for the buck vs vents, especially since this setup is not geared towards frequent flux venting. If you wish to change the dual MGs for revolvers though, you will have to put the OP on vents (since the accel shields are put in to save flux also).
Lastly, the sabot/harpoon combo is devastating when used properly. Due to the difference in speed between the 2 missiles, it is very possible to both overload the enemy hull and hit it for 1500pts with the same missile salvo. It is a little tricky to perform (and a heavy needler would be a better candidate for optimizing the strategy), but when done right, it is damn impossible to wipe off the grin in your face...XD
