Using 301s to get deep links

[Tacit]

Hey guys,
I've had an idea bouncing around in my head for turning homepage-only directory links into deep links. Lets say I have a client who trains a wide variety of pets. There are some dog training specific directories who will only link to a homepage (no deep links). So I get an exact match domain like dogtrainingcourses.com so that I can use 'Dog Training Courses' in my business title (which becomes the anchor text), get a whole bunch of these to my my site (simple 1 page wordpress site).

Then do I:

A) simply 301 the whole domain to my clients deep page on dog training courses. I assume that majority of the link juice will pass, but how about the keyword relevancy?

OR

b) Rather than 301ing the whole domain, just have a single link on the homepage with 'dog training courses' linking to clients deep page (like a doorway page). Only trouble is I don't want this buffer site to rank (which it no doubt will).

Oh and please no one start arguing that directories are useless etc, focus on other types of links etc.

So basically you are going to link from the directory ==> Site A ==> Client's individual page.

Instead of having Site A in the middle, why not just link to the client's homepage and have a link from the homepage to the individual page?

Directory ==> Client's homepage ==> Client's individual page

You are building up the domain that way, increasing the power of its internal links, and eliminating a useless extra domain.
