hello, I read that AD is being sent to Israel, the experience we have is sending AD to a DRY environment is a guarantee for problems, although ipe wood is very very stable, it is still wood and so prone to the elements. Therefore, KD decking is the only appropriate product for this dry region otherwise you may expect some % of your boards converting into banana shape, especially the longer lengths.
In order to avoid cracking you should always wax your ends and in order to avoid the greying use a UV filtering coating. See for more on finishing and coating of your hardwood decking by clicking on this weblink
