Thanks to limmy for some info.

I have tried
oils : GPL100, 103, 105
grease : 240AZ, GPL201, 203, 205, 226
100 worked just fine in normal switches. However, it may have durability issue because it evaporates quicker, but 100 is the oil with least viscosity so it doesn't change the feel as much as other oils.
I have been running an experiment on durability of GPL100 over 2 months. So far about 30% weight loss has occurred over two months. I spread 0.10g of GPL100 in an open container and I tracked the weight over two months. After two months, there is 0.07g left. The scale used in the measurement is a cheap Chinese jeweler's scale, so the accuracy could be an issue, but I see downward trending in many measurements so I am pretty certain that 100 evaporates in normal temperatures.
GPL105 and 106:
105 worked fine too but if applied more than necessary switches felt slightly sluggish. 106 variant was once popular in OTD, so I know 106 would also be usable if applied sparingly.
I have 103 at hand, but haven't used it for long enough to say they work well. However, I hear success stories from other users so I think it works just as I expected. I was the one of few people who provided information on Krytox for members of KBDMania and I believe I have contributed quite a lot in the choice of Krytox oil(GPL103) in recent group buy in KBDMania.
From my experience, I could get impressive results by applying thin coat of Krytox grease and applying oil on top of the coat. Grease adheres to surface and holds the oil in place, while if only oil is used the oil tend to run. Running oil is less of an issue in Cherry switches because the sliders are in the slider housing hence holding the oil quite nicely due to capillary action between the slider and the housing. Running oil was more of an issue with Topre switches because most of the slider is exposed.
Luer lock oiler (sold in 10) + luer lock cap(sold in 50) See http://jensenglobal.com/
32G blunt needle (32G may be too narrow for some because you really have to squeeze to get some oil out out that needle. 30G might work better. Sold in 50 or 20) See http://jensenglobal.com/ or search "32G blunt needle" on ebay
I think GPL103 is a nice choice. Just be careful not to over apply. I don't think brush container is a good choice because I feel using the brush will apply more than necessary oil. (You want thin coat) I think precision oiler with thin needle(greater than 30G) is better choice.
