Thanks for the feedback. I am pretty happy that I changed from Maru to silicone oil. My Cubicle weigth 1 & 2 syringes are on their way and I can't wait to try weight 2. For now I'm more than satisfied with the performance of cubicle silicone but, of course, I'll have to wait and see how long it lasts, etc. For now, the 2 cubes I lubed with wt 3, the more I use them the better they feel.
The feel is also very consistent. The worst thing about Maru lube, now that I look into it in restrospect, was not that it lasted only one day but that, e.g. if I was going to do an average of 100 and I lubed right before starting, by the end of the average the feeling of the cube was already significantly different (drier) than at the beginning of it.
