No apologies necessary.  It is useful to explore the various 
flavours, I think the best advice for the OP (which others have given 
as well) is to check out the SpamAssassin users list archive, as this 
has all the rules and discussions about the pros and cons for them.

The basic rule that I used worked well for my site, until Bayes and 
URIBLs caught up.  and we didn't get any of the non-uk variety 
getting through, so I didn't 'upgrade' my version of the rule.  In 
fact I suspect I could stop using it now and not notice any drop in 
quality of filtering.
