Probe is stringy, but it's also one of the few water-based lubes that I don't react to. A burning butt during anal play is no fun. It's also fairly cheap, a nice plus.
I tried coconut oil and moved away from it. It melts and becomes too fluid for comfortable anal use in my opinion. If you want to do a homebrew lube melt some coconut oil and mix it with Crisco, then it's thick enough to stay around.
Oil lubes are nice because they tend to stick to silicone well, but cleanup is hard. Water lubes work pretty well and cleanup is easier. I use a thick oil-based lube for big toys and usually water-based lube for everything else. I've found that silicone lubes sometimes do strange things with silicone toys. Usually non-permanent (provided you have good silicone lube and good silicone toys), but it seems that the lubricating power is often reduced, and sometimes my toys develop temporary "welts" or "hives".
The best way to do it is to get as many sample packs as you can and try them out yourself. Pick one you like and stay with it.
