UM2+E jamming mid print with .25 nozzle.

There is probably something simple I'm missing, but I've already tried Googling, but that hasn't given me much. 

I've used the stock .25 nozzle a few times before, but they always have been relatively small and quick prints, no more than a few hours, and .2 layer height. 

Now, I'm printing a pretty intricate and delicate model that needs a .25 nozzle and to print at .1 layer height, and even with a UM2, I feel like I need to print extremely slow. Every print attempt jammed at a random point. The kind "jam" where its not really jamming, and the edge of the filament, when pulled out, is thicker and kind of flat. 

I read that going too slow with a small nozzle can cause this problem, but it jammed at my last attempt at 45mm/s. I previously tried 15mm/s and 30mm/s. The print going at 45mm/s got the furthest along. I'm just too afraid to go any faster. The model is a female character figure with a thin skirt that flares out that needs lots of support for (I did everything I can to thicken the skirt area in Blender). 

Is there something I'm missing, or am I thinking too hard into this and just should increase the speed? Thanks!
