As soon as I tried type c controls on the Resident Evil Revelations demo I wondered why anyone would even consider the circle pad pro. It's a pretty versatile control scheme. It allows moving while shooting with ease and I find myself pulling off headshots and pinpoint aiming easier with said scheme. Hopefully Metal Gear Solid 3DS will have a similar control scheme to control type c.
Edit: Meant circle pad PRO in the title.
