I don't know that there is a good answer here.
At this point I think I prefer Harbour Station (at the time of the switch I didn't think it was a good idea). Facilities, Committee, etc all seem to be a little more professional and controlled then then Atiken. Much less crowd issues then their were in the last few years at Aitken+ having the bigboard and nicer seating makes it a more pleasant fan experience. Also the lack a difference/space between floor and bowl seating makes it feel a little closer.
I'm all for giving chances and opportunties, but I don't think it should be moved around for the sake of moving it around. If you can get a site (Fredericton, SJ, Bathurst, etc) that can offer services and a product that enhances the basketball experience and community then that is where is should be. If someone comes up with something better have it there instead. Don't move it just to say it moved though.
The only issue that I think you would want to make sure of is that the location wasn't providing a distinct advantage or disadvantage to a region. I'm not sure the SJ sample size is large enough yet (10 titles handed out at that location) but 50 % have gone to Southern Zone schools. I'm not saying there is a conspiracy theory or any advantage in it being at SJ for southern schools, as I stated the sample size is much to small and over a very short period of time. I think it would be interesting over time to go back over the data from Aitken (maybe even before Aitken when schools hosted provincials) and eventually make sure that the numbers come out in the wash to say that the location isn't generally a factor. SO far at SJ 5 southern conference winners, 3 western conference, 1 north, 1 east. Two years previously at AC 8 titles handed out 4 west, 2 east, 1 north, 1 south. 50% coming from regional host but again really small sample sizes I'm sure its nothing to worry about? ;!
