Re: 2 Q's
For some of the other extra strong working oils, I really liked avocado oil and walnut oil. From the reading I've done, people tend to think the avocado and castaor oils are the most powerful, and avocado being slightly more so than the castor. However, avocado is harder to find and more expensive.
I think the avocado oil has a nice "green" taste. It is a thicker oil, and must be refrigerated. The "green" taste does taste like avocado, or even a little like asparagus, I think. Would have been great on a salad, if I hadn't been pulling with it.
The walnut oil, is lighter, and I don't think it has much of a taste, though other people do think it has a nutty flavor. Maybe I'm too used to tasting the nut oils, so don't notice the flavors much. I bought my walnut oil in the Kansas City area when I went to visit family (thus my 6-hour drive pulling with walnut oil on the way home, mentioned in a previous post today). I used the avocado oil exclusively while visiting, until it was gone.
Next in line to these three oils is the coconut oil. That's the main one I pull with right now. I'm pretty rural, so getting the specialized oils is hard. I did finally find a source for sunflower oil (hadn't been able to find it anywhere) and walnut oil within a 40 mile drive, so will be trying those.
I've used safflower oil, since I can't get sunflower. I like it a lot. It's my second favorite, and I think in my case is very similar to the walnut.
Besides some blends, I've also used extra light olive oil. It's my least favorite of these mighty 6 oils (I haven't tried the castor yet), but that's because I have a harder time getting it to thicken. It works on different things than the other oils, so you might want to consider using it, too. The extra light has almost no taste. I get a gag reflex for the virgin olive oils because of the taste. Too much reminder of liver flushes.
For the oils I can get hold of here, the ideal for me is alternating between the coconut oil, walnut oil, safflower oil and extra light olive oil. I plan to add the sunflower oil when I can get it (or substitute it for the safflower).
