Jeroen,
you are well informed. I indeed recently presented during the Colt Cup (an annual match between the Dutch Colt Courses, Haagsche, Kennemer, Pan, Eindhoven, Dommel and Hilversum).
Topic was Colt's design filosofy and how certain holes on the various courses fitted those. I let the clubs pick their own favorite hole. The ones they chose were:
Eindhoven hole 3
Pan hole 15
Haagsche hole 15
Kennemer hole 9
Dommel hole 5
Hilversum hole 16
If you give me your contact details I would be happy to send you a CD Rom with the Powerpoint presentation on it (file is 32 Mb, a bit too large to e-mail).
