Envelope bagging

I've been trying envelope bagging recently and have decided to revert to taping my bags to the flange. With envelope bagging it's easy to set up and get a leak-free seal but I got bored of sanding resin ridges from the back of the mould and I was using twice the amount of bagging film. Has anyone else tried envelope bagging and preferred it?

I only envelope smallish moulds ... they are all made with the EC Epoxy Putty ... I just leave any resin on the reverse side there ... Just lazy I guess ...Whistling
Usually I do not get much, if any resin on the back side of my moulds ... I sand away any sharp resin ridges, it they are a problem.
