I've found SPF has helped my spam filter immensely just by blocking spoofed senders. It's not a cure-all, but it certainly helps and you can use it to increase your spam collection for better bayesian.
The only problem I encounter with restrictive SPF is when someone starts using a different SMTP.

CipherTrust's research among users of its own IronMail message security appliance this summer found that a spam message is three times more likely to pass an SPF check than it is to fail it." I really would welcome a new working anti spam or phishing feature. Sadly SPF isn't one of them and never will be.
