Every software application update comes with fixes and new issues.
Does this involve a server upgrade? Then plan an upgrade to SR10. You'll have ample time to evaluate SR10 for adverse effects and poll the community on that subject. Because what will you do if SR11 is released only a week before your planned upgrade? Just do the upgrade without risk assessment?
If it doesn't involve a server, install every new SR when it becomes available. You can easily go back if things turn out to be different than what you expect.
