If you want good flashbacks, you need good writers. Lost had good writers and good flashbacks. For the reverse example, see The Event.
Since Stargate has never had very good writers (certainly not in the past ten years or so), the answer is not to add flashbacks but to hire writers like they had on Lost (if they could afford them, maybe that's the problem). Then you can do flashbacks or flashsideways or whatever you want.
all flashbacks do is ruin the flow of the tv show. If you got a good story to tell then you dont need flashbacks or flash sides ways. Keep it simple with a good story.
