So you're saying that if this isn't the kind of diving you do, then 
80/20 is fine?  I'm not convinced on the "it has nitrogen in it" 
argument, that's a rather complicated issue about which not all that 
much is known (decompression theory).  One of the big problems with 
the DIR people is that they are unwilling to accept that some 
situations may require a different setup, or that a different setup 
may be more ideal in some situations.  Not that I think 80/20 is 
better, I just think your arguments aren't all that convincing.

BTW, could you guys take the extra 2 seconds and cut off the part of 
the reply that isn't relevant?  We've all read those other 15 
messages, no need to quote the whole thread every time.  Thanks.
