I don't dislike the match for the unnamed WWW but personally I would try to find a higher ABLB boy to throw her at. However, if Alexander is all that fits in you budget he matches nicely.

I wouldn't do either of those for Depths of Dispair. I would find a ABLB boy for her.

I like Alexander for Scent of a Woodwick.

I would find a WWW for Candle in a Window unless you are specifically trying to get that stallions bravery.

I am very worried about Spd on Ayelet HaShahar's match. I would probably try a different stallion but if you are going to do that one definitely do a item to cover Spd.

I am happy to help more once I'm off work if you still need it :)
