Pros/Cons of Different gear set-ups

[durr]

I have been looking at different mixs and gear set-ups that rogues can have for combat spec. There was one set-up that looks likes could be a better set-up then the one used by your current combat rogues.

This players set up listed above, looks like if actually might be better by just looking at the stats. More ap, higher arp, and hit. Stats that are usually important for combat rogues. I was hoping you could go in depth in why you have chosen to go with the gear you currently are using, and the pros and cons of this other set-up listed above.

Can you base your statement on anything solid, instead of "those stats are good"? I'm always using the best set of gear that I have at any point in time. What other justification to wearing something is there? :P You can probably think of the pros and cons with the set bonus yourself (hint: 13% proc =))

By looking at the sheet I can find out that his choice (with a heroic ikfirus) turns out about 0,1 dps ahead a set which replaces his stuff with t10 chest and pants. The gunship cloak is better than the toc one for a short time after you get STS, but when you start getting the other 2 284 parts from halion the toc cloak and tier pieces get a considerable lead. Even more so with an orc.
