Hey, I have been using the sensei for a long time until it died. Recently, I tried the nixeus revel and liked the shape better than sensei ( feel a little smaller and fits my hand better ) but not the mouse buttons. They are too sensitive. I play cs go and it's harder for me to tap firing continuously. So I'm looking to try the fk series since I heard they use heavier switches? Is it true? Should I get the fk1 or fk2 if I really like the revel' shape? Also, did zowie upgraded their fk series with 3360 sensor like with EC? I use palm grip and my hand size is around 16cm.
