backburner pyro map specific strategies?

how are you able to play it on a map like gravelpit? I can handle large games easily enough but suppose it's a fairly typical 6 vs 6 setup of 2 soldiers scout demo sniper and medic how are actually meant to play it effectively? I had som success with occasionally getting behind the medic and the sniper but otherwise my play style of "spy without the cloak or disguise" is prety fail.

I love using the backburner on gravelpit. But in a smaller game of 6 vs 6 it can be harder to ambush effectively because players tend to watch eachothers backs more often. Try attacking from behind while your team mates attack from the front. This would at least insure that the enemy team would have to deal with being attacked from two sides at once.

You should post a demo so we can give you more specialized advice.
