well increased static sag won't help much, and shortened suspension isn't required IMO, it just needs setting up right. They might have just dropped the forks through the yokes for all I know
What you want is adj suspension front and rear so you can set it up to your requirements.
Not really sure why you are asking about another bike if you already have a bike - if you want advice on setup of your current stuff then let us know and we can try and help
