I need some advice about whether it's worth installing JoomSEF (for Joomla 1.6) or simply to add a rule to .htaccess instead - this is a single URL problem with Joomla 1.6 adding the Itemid to 'SEO-friendly' URLs.

I have a series of sequentially-numbered items in several named categories, which appear as numbered lists on this page. However, the added article ID in the URL is confusing the client...

I need this: vision2020.org.uk/wishlist-for-retail/131-16-local-shops.html

to become: vision2020.org.uk/wishlist-for-retail/16-local-shops.html

There will never be any URL clashes, as each item always has a unique number in the title.

Would it be simpler to add a mod_rewrite rule manually - if so, any suggestions? We only need this one change for the site to be complete.
