Jeff, I'm not sure if you mean 5 courses that each demonstrate variety within the course itself or, as I interpreted, 5 courses that together demonstrate a variety of architectural styles.
By far, I know William Flynn the best, so here is a list of 5 courses showing his abilities on a variety of sites:
Shinnecock Hills
Boca Raton South
Huntingdon Valley
Eagles Mere New Course
The Cascades
Flynn is best known for his parkland style courses, and I chose HVCC as an outstanding representative of this style. Flynn's work at Shinnecock presents a hybrid approach that is not entirely links style. I chose the NLE Boca Raton South for a seaside style course. The Cascades is an engineering marvel that looks natural in its mountain setting. Within this one course, Flynn's design variety is evidenced in the different approaches he used for the hill sections and the flat sections. Eagles Mere New (1925) is a minimalist design that shows his ability to brilliantly rout under extremely demanding topographic challenges on a mountainous site.
The use and look of hazards varied with the type of site he was working on. Far from a homogeneous body of work, the entire Flynn portfolio is varied and strong.
