Don't know how many Home games you have been to Dave but there hasn't been any trouble along the back of the Lyndhurst this season and we have hosted Leeds (×2), Millwall, Cardiff, Bristol City, et al.Strangely I almost agree with IJN!
Taking the emotion out of it all, if that's possible.
At the moment, you have the Away fans walking along the back of the Lyndhurst, through the home supporters. Likewise after the game the same. If they were in the Demport End, their coaches could drop them off right outside, straight into the ground, then straight back on the coaches after the game. That makes complete sense. Now the segregation, in the BP end we usually lose around a thousand or more seats, which is ridiculous. You see Manchester, Liverpool & other derbys with just a line or two of Stewards or Police. But if they were in the Demport you have a natural part over the tunnel,using about 150-200 seats. So more seats available to sell. Plus the changing rooms, our players having to walk past the away fans, which at times won't be easy.
But then there is the emotional tradition of being in the Demport. Logic says it's a good idea, but emotional maybe not.
I'm a Lyndhurst ST holder and I haven't seen any trouble.
The only hint of trouble in recent seasons has been when the Stone Island brigade get all excited when we play Exeter, but that's mostly school kids trying to look hard.
Also, the vast majority of Away fans don't come in Coaches anymore, they make their own travel arrangements. For all of our fantastic Away support this season, how many Coaches do Argyle put on?
As for the size of the segregation area, I believe that is the Police and others rather than Argyle who decide on that. So moving ends wouldn't necessarily alter that.
The tunnel location is a complete non-issue. Some people seem to imply that the Away fans are the only ones making any noise as the players come out and the Argyle fans are silent, which of course isn’t the case.
All the players must hear is the combined sound of all of the fans as they come on to the pitch and 15000 Argyle fans ought to be able to make more noise than 1600 Away fans, as they do.
There is also Semper Fidelis blaring out as the players come out of the tunnel, so I don't think the Away fans have that much effect.
