I'm currently using a Pentel brushpen "FP5F" which has a very pleasant feel and steady controllable ink flow, recommended if your looking for a cool brushpen that won't go into blotch mode while you're desperately trying to draw thin lines. It still takes practice to get used to it though ;)
And the yellowish paper of the Moleskine sketchbook has a very soft anf thick feel which makes brush inking on it like skating on ice.
While I was still trying to draw the usual stuff I feel safe doing, I tried to get in gear working on paper again and have some fun as well. Hopefully I'll get more ambitious when the last pages are filled and I start on the new sketchbook I got which is twice as big.
