It depends, I use stearin and vybar together sometimes as stearin really aids the candles release from the moulds but tend to find if I am making a really dark candle the mottling that stearin causes is really noticeable so I just use vybar. Just down to personal choice I suppose, I don't really have a preferance. The scent I was using was Angel Type. I love the perfume and love the candles smelling of them but it is a real bugger trying to get the scent and wax to combine and not leak. It is a really dark coloured FO and I don't know why but the darker FO's tend to need less used and are harder to combine. Just whisk, whisk, whisk. All the best. Lisa
