Large site rel=can or no-index?

[cottamg]

Hi,

A large site with tens of thousands of pages, but lots of the pages are very similar.

The site is about training courses, and the url structure is something like:

training-course/date/time

I only really want the search engines to index the actual training course pages, which is the better option for me and why?:

a) rel=canonical

b) noindex, nofollow

Thanks,

Gary.

Option A seems to be the best option as it can pass linkjuice you could get on a deep page (training-course/date/time) to the main course page.
