Any chance we could increase the chip stacks to 5,000 for this event? 
I"m going to request the same thing, and try and give a good case as to why. The same ideas apply to the Stud event too.
Basically its well known that in any Limit event, the average stack for the middle-late part of the tourney is 10 big bets. This is the natural point where you have enough short stacks that people drop out regularly.
Therefore, if we assume the event will be full there will be 50 x 3000 chips in play: 150,000.
If you assume we get to 4 people left, they will have an average of 37500. Therefore by level 14 with limits of 1500/3000, they will have less than 10 big bets each. Because the blinds double within 2 levels after this, going to 2000/4000 then 3000/6000, the tourney will not run much longer than this.
If we assume there is not an abnormal heads up match, it will easily be done before level 16, 4000/8000. This is of course a total of 8 hours play. Dont get me wrong, for a stud and a razz tournament to be in the UK is reason enough to be happy. And even the structure as descirbed above is not bad.
However, my proposal is actually to increase the stack to 4,000, believing it not just be be a round number picked from air, but an increase that gives a little extra playablitiy to the tournaments, and does not lead to an excessive finishing time.
This is becuase, with 50 runners at 4000 chips each, there are 200,000 chips in play. Therefore when 4 handed, average will be 50,000. This means the 2000/4000 and 3000/6000 levels still retain some play. I would expect this tournament to be completed before the end of 8000/16000, and it will pretty much never get beyond 10000/20000, which is 10 hours of play. Even with breaks, this will not take the 2 lucky heads up players beyond 2am. Sure thats a long day, but how often do you get an opportunity to play these events?
I hope what I"ve said makes sense (and that its correct!) and I hope the APAT will consider my thoughts.
Look forward to the day.
