Seat choice at falmer!

I have heard that the presentation visits do not allow you to actually choose a seat, only the stand you want to sit in, is this true, if so there is no real advantage in visiting in early Jan over end of March or even just putting your ticket application in now.
How do you request a seat in a certain area of the stand or is it just pot luck? (or does it depend on you paying for a PSL to obtain a specific seat!!)

No, you have a digital seating plan and you are able to pick from those available - and PSLs do not make any difference to seat choice.
