That is Kaiser's opinion on the timing tools, and he is more than welcome to give it.
The alternative view is that the only way to ensure the timing is correct is to use the timing tools - you should be in the ball park if mark everything up though.
The discussion on whether to use the tools or not has been done to death on here and elsewhere, so we might as well agree to disagree.
It isn't just a Rover thing - did a cambelt on a Citroen DW8 last night, and both the cam and fuel pump sprockets float so you pin the flywheel, cam and pump sprockets, tension the new belt and then lock up the sprockets.
The good thing about the DW8 timing pins is that you can knock them up yourself.
