I do all my AK mousing these days with a 5110 switch rod...I'm sure your 4116will work well too. I usually use a standard WF7F or Rio 5/6 switch line, using both overhand and roll casts. Have also used a Skagit head/floating tip (a floating mouse doesn't really hinder a water anchored cast), but I prefer the full standard line for mending purposes and imparting that "mousy twitch" to the fly (holding the rod tip high, twitching the tip, swimming the fly thru good holding water, slowing it down with mends).
