Adding a Rudder to my Mill Creek 16.5...Question

Hello All,

I built an MC 16.5 two years ago with the intention to row it.  But, I never bought the rowing unit or the oars.  When paddling as a kayak, it tracks straight and is difficult to turn.  I want to add a rudder kit to it.  My question is about the foot controls.  Can I mount them in either the fore or aft seat position?  Which is the preferred position for them?
