Perhaps if would be useful if Mr. Durden read the 2006 NOTAM (easily found with a Google Search).  It's so easy for a PNF (Person Not Flying) to criticize.  Sorting thru its 32 pages of complexity, I will focus primarily on arrival speeds.
 
The "FISK" VFR arrival requires that one fly at 1800 MSL and "..maintain 90 Kts or MAX CRUISE SPEED if less than 90 Kts" (emphasis added).  Otherwise, "..if unable, maintain 2300 MSL and 135 Kts."
 
The Turbine/Warbird arrival is not limited to warbirds as can be read in the title.  It is for warbirds capable of cruise speeds of 130 Kts or greater, leaving out those WWI/II observation planes that can only reach that speed in a dive.  It is also for high performance turbojet and twin turboprop planes.  Note that leaving Warbird Island, the speed is limited to less than 150 Kts.  Maybe the "warbird" arrival is the safest procedure for the latest breed of high performance aircraft - Experimental Amateur Built aircraft arriving at a fly-in sponsored by the Experimental Aircraft Association.
 
Where can a high performance prop airplane fit in?  I've tried the 90 Kt arrival and will never do so again since the mix includes slow flying craft that the pilot never had over 80 Kts.  I've tried the 135 Kt arrival and it should have worked out except once I was stuck behind a pair of twins that seemed to be hanging on Vmc.  Why does everyone think this is an exercise to see how slowly the arrival can be flown?
 
Where do high performance aircraft with cruise speeds in excess of 180 Kts mesh safely?  The 2007 NOTAM will have to address the arrival procedures for Very Light Jets (VLJs) that stall at higher speeds and Light Sport Aircraft (LSAs) that are limited to a max speed of 120 Kts operated by Sport Pilots with a minimum of 20 Hours of training to get their ticket.  Uh, how about "fat ultralights" converted to LSAs dragging around N-numbers at very slow speeds?  Sounds like the low altitude FISK arrival is going to be very crowded.
 
I've happily solved my arrival problem by diverting thru Dayton and joining the AirVenture Cup Race gaggle.  There is nothing like a flight of 60 planes, sorted by speed, flying into OSH from the Fond Du Lac race recovery airport.
 
PS:  You cannot rely on any information from a prior year's NOTAM.
PPS: Go Scotty G.
