I would have to say that the current Captcha must go. It took me atleast 10 tries to get past it. 
If your into hacking the Captcha yourself the main part is ok, but the one part that I had a problem with was just a line(it just looks like a l or an I, but neither of those worked, it sent me a captcha with the same line in it a few times and I tried a bunch of things for that letter but couldn't figure out what it was).
If I knew more about SMF I would help you, but I am a phpBB modder. 8)
