Drawing on his 28 years of tying experience, Malcolm designed the patterns used in his best-selling book Mayflies, co-authored with Robert Cormier. Five years after it was first published, the book remains the definitive resource for understanding and imitating this insect. Before Gary Lafontaine's untimely passing, he and Malcolm had spent time compiling a new book of their favourite Mayfly patterns.

Trout have been a lifelong obsession for Malcolm. This passion is evident in Malcolm's favourite fly fishing destinations, which he narrows down to three top picks: the Bow River for big Trout on a streamer, Crowsnest for spooky Trout on a spinner Mayfly and Henry's Fork for the Green Drake hatch.
