Not saying that at all Pascale - Im saying it is a choice depending on your equipment, end product and intended use. It has to be made in an informed way which is the best system for you to be working with, they both have their own advantages and disadvantages which you should be aware of before making the decision.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
