Ugh yes that's a horrible feeling. T^T Desperate clicking and shaking, hoping you are mistaken and there is actually one last lead left...hunting around in your pencil box for the lead case and wondering if you ran out...
Clickies are the best for drawing. You keep a nice, small tip rather than having to go sharpen it a dozen times. You can also stock up on your preferred lead very easily; I admit to hoarding clicky lead like a crackhead.
Yes, I love the consistent lead size. ^^ And there's still a little bit of "play" to be had. If you use it at an angle for a bit you can get a super-sharp edge and a little bit wider flat head too~ Ahh, I love my clicky pencils~ <3
They do indeed. When I sketched with regular pencils, the line thickness would be all over the place as I blunted a tip. XD And then after I sharpened the pencil the lines would be super-fine and sharp again...and then begin to fatten up and blur... orz
