At this point all I have to say is that very often we get offended by other people because of our own perceptions and not because the other person is actually being rude. Many times we are offended by what the other person says simply because we choose to be offended. In most cases it really is just a matter of choice and we have the choice to be offended or not. Not everything is going to be said in the manner that we want it to be, so try to be a bit more tolerant of other people as I can say for sure that no one is actually trying to offend anyone else. If you want to be offended by the way a person says things, do not go on an attack on the forum deal with it through the PM service or let it go, the forum is not really for a lot of discussion about how rude you think someone is, it is about helping people with their parrots.
I have a couple of the java perches and they should work great for your birds as long as they fit the birds feet. that is the biggest issue when buying them online. Another thing that I would consider is that with the larger birds you may want to get them long enough to reach across the cage so that they can be supported from both ends and not just one. Hope this helps.
