I don't understand what you'r saying. The Saber has 2S3 fixed and 2S3 Gimbaled. That's 8 S2 slots. If you use all Sledge II's you pull like I,600 power, but they never overheat. There's a question how much ammo you can carry, but that seems secondary to me. Some of the nice things about the Sledge are good damage, very fast to target means more hits, and incredible range. I am just thinking how to use the limited stealth to best effect, and if others can't lock on you out past say, 4 km; the Sledge is a super choice for multi-mission capability. Also they have the lowest idle power of any weapon, so they help with stealth--you will have lower EM and IR signatures when not firing than with any other weapon, and even that small signature you can eliminate by shutting them down altogether, since the Sledge has an extremely short charge time (just 2 seconds). It's a great stealth weapon from what I can see, especially if you want to use your stealth to fire while off your opponents screens.
I am also very interested to hear about shield charging time. Do the kinds of weapon one is running and their power draw affect shield recharge times? What is the Sabre's shield recharge like compared to the Hornet and Buck?
