I myself use two brand's. But always the same ratio. When I'm in the mood for a fragrance I love Klotz with Castor, then I add a cap full of cherry fuel fragrance. When I'm more of in the mood for old school smoke I use Lucas semi synthetic. As for ratio I always stick with 32:1 always. Hope everyone will chime in on this thread and let's drive the replies threw the roof. Have a great day. __________________________________________________ Felt deep 6, boardtracker, 66cc.
