Got very little to do with the film, and everything to do with technique. Softer films can be easier to use, but they are also easier to puncture, so it's a trade off. But you should not have to rely on the bag stretching to solve bridging, so I prefer to have a more rugged bag that you can push into the corners with as much force as you need and worry less about putting a hole in it.
The film's that EC supply are a great option, they are relatively soft but but still quite tough.

Yeh EC are great. Super easy, and their pricing is rock solid - even for me in Aus paying the horrendous exchange rate and freight. If I was in Europe, I would get everything from them too.

I kinda disagree here as i had way more trouble with leaky bags with rigid films that then like to crease and when you push that crease around it can damage the film. Loved the strechlon 200 but didn't work with it for years now due to availability as well.

Yeh personal preference will play a big part in it, everyone has their materials that they like to use. There's advantages and disadvantages to all of them, and no real 'best' solution.

I have given them a fair amount of abuse and the only problem has been very sharp mould edges which are quickly solved with bagging tape.

No wasn't Easycomposites bags Was mostly when working at clients workshops and have seen a couple of weird bags.

I can piece together most things from all over the country, but it's taken a long time to build those networks. Australia is very behind the times with composites, for the most part the industry is still pool builders and boat builders. Some of the boat builders are doing very advanced stuff, which is why these products can be sourced if you look hard enough. But it makes sense; Australia is a bloody massive place, very far away from the rest of the world, and the market is very small. I certainly wouldn't want to be in the supply game here.

If you always cover up the edges of the flow media, the bag doesn't seem to be that tough. I never had to do that and didn't have problems at all. And I used the "standard" heavy flow media quite a lot.
I use a pa/pe/pa type bagging film.
