I guess you just have to adjust the weapons to drain your energy at a rate that's comfortable for you. Some people like to do as much damage as possible in a short time, regardless of drain, hoping for a quick kill. Myself, I look for weapons with high efficiency; and other than the nomad weapons, that's the Wild Fire guns, hands down.

Oh, and people are always comparing the VHFs on their agility, but they don't often talk about their power systems. The Sabre has more power than the Eagle, and the Titan more than the Sabre. A classic trade-off in power vs. maneuverability.

sabre is better all-round though because titan handles like a drunken mule whereas a sabre handles better and is also more powerful than most ships in every way (short of defence on the titan pretty much) i personally wish titan was something like a freighter... it would have massive defence and because freighters aren't meant to handle that great anyways as they are cargo ships, it would make a good freighter (of course it would be have massive cargo as well)
anyways thats just a random thought considering how dromedaries are the best freighters and they can handle up to lvl 6 weapons

Dromedaries can carry a little more cargo than Humpbacks, but they have a weapon class limit of 5's and 6's, while the humpy is 6's and 7's. The game designers weren't dumb, there are trade-offs for all the ships; there is no "best". And in saying the Sabre is better than the Titan in everything but armor, you're ignoring the Titan's superior weapon power... which so many people seem to do, probably because Nomad guns makes it of no importance.
