Flameon: I've been experimenting a little recently regarding the saturated vs. unsaturated oils, and I've got some personal experience that backs up everything you said

Last weekend I ate a single slice of pizza for dinner, and to finish the meal off I dipped the crust in olive oil spiked with about 1.5g of bud, via the double-boil method. This was at 6PM.
T+1 hour: I was not starting to feel anything, but I wanted to see exactly where it would take me, so I did not join my brother & friends in the smoke session.
T+2 hours: Still not feeling anything, decide to have a drink with everyone else. I had about 2 shots worth, for a minor buzz but nothing crazy. Also had an energy drink.
T+4 hours: Sobered back up from the scotch, and noticed I was starting to come up on the weed high. It was just barely noticeable at first, and 99% body. By the time the alcohol wore off, I was almost completely clear-headed, not giggly.
T+6 hours: Body high starting to plateau into a full-on skin-tingly buzz. Heady high starting to kick in. Shared a cigar to celebrate the end of Ramadan with our Turkish friend.
T+8 hours: Still high and energetic, with no indication of slowing down.
T+10 hours: My mind started to get tired around 4AM, but my body was still stoned out of its skin. I don't enjoy going to bed high, as the skin-tingling effects make it difficult for me to stop tossing and turning. But being ticklish is sometimes fun ;p
T+16 hours: I woke up at 10AM, still about a 6 on a scale of 10 regarding the body high. Mind was totally clear and alert. The gradual comedown left me with a really good Saturday afternoon and evening smoking with friends.

So I think I'm going to have to get some high-saturated coconut oil for my next batch, and see how quickly that hits me
