Gday Rob
well i use both , i use veg tan dry for my bosals and use my own platting soap as i go , because drumed will bleed then whisky turns in to Brandy !!!! What the !!! but if i am doing a whip that is 1 tone belly it doesnt matter but two tone i will go the dry then add my soap to plait with
I all so use my soap to plait whips with even if they are drum , stuffed ,, it helps them strings to pull tighter , they slip up nice and tight with a bit of soap , "mutten fat and lux soap flakes "
I am sure you have your own Rod
cheers
