[TheForge] Air Hammer Air Schemes

[Phil]

My apologies for interjecting a blacksmithing question
on theforge.

I've built 3 kinyon style air hammers, all using the
air scheme on the Alabama Forge Council web site at:

I'm getting ready to build another.  I've been
considering using the air scheme represented by the
parts list on Dave Mudge's web site at:

http://magichammer.freeservers.com/pdi_quotation.htm

Has anyone seen both of these air schemes in action? 
If so, could you provide your opinion on them (pros
and cons)?

Thanks
