Hmm i think you will not gain any link juice because your anchor text is just a letter. You can still have the backlinks with no importance. The googlebot will crawl this link but your target link woldnt get rank..
Anything that is not to do with good content for others to enjoy and benefit from will not ultimately get you anywhere.. stop trying to find sneeky ways to boost traffic and PR and do it correctly and honestly you will be rewarded for that....
Tried it once before I knew about SEO on the advice of a fellow worker, the website got slapped quick and hard.
