I have a large bottle of j-lube powder, so I can make it as thick or thin as I want and I will try it in various ways, but want a good general starting point.

J-lube is under $20 and makes about 6 gallons just by mixing with water, if anyone is interested.

I tend to prefer something a bit thicker in my fleshlight, but I'm ordering some onaholes to try out soon. Getting La Bocca De La Verita and WAZ Daruma-Gaesha.
