Not familiar with the rulers you mention, but I usually use a straight ruler that is about 10 (?)inches long, a gentle curve and a Westalee ruler that makes circles. I have others but I rarely use them.
You don't want a ruler really long because it will shift on you and you want to be able to keep an eye on where it ends.
I also have a little measuring guide thingy that you use to make sure you are 1/4" away at the far end, which I find helpful.
The main thing I really have to watch is that I keep the foot against the ruler and don't let my mind wander, because then the foot will too!
