<font color='#0000FF'>rob,
agree with the thinking &quot;helium is best&quot; but i think that is just a school of thought rather than anything gue teach,maybe it is?
i think ccr takes a key consideration for o/c divers out of the equation &quot;helium costs&quot;.

does anybody have any other thoughts?

cheers
