Mike

I've been using the TX50 for many years and it is excellent.  I have now
moved that to my stage cylinders and use two TX100s (flathead 1st stage) on
my twins.  Again,  superb breathers.   There was a design fault with the
original TX100s, this was picked up very early on and has since been
corrected.

The flathead does remove the O ring in the swivel which can only be a good
thing even though I have never had any problems with it.  Hose routing I am
still perfecting but, by attaching them horizontally the ports guide the
hoses down the side of the wing very well.  I'll post again when I'm
completely happy - anybody else got a neat solution?
