Gemma- I am only using a bumgenius version 3 with the large bigger weeds hemp pad and the large microfibre pad that came with the bumgenius. I also use bamboo/hemp baby beehinds which is very good with a couple of the bumgenius micrfibre inserts and fleece liner. I think it's the hemp that's finally won the battle. The bigger weeds is huge like a pre-fold, I fold it in 3 and stuff it in my pockets.
Keep trying, eventually you'll get there
