htaccess rewrite rule - optional trailing slash

my client has requested that a URL work regardless of whether or not there is a trailing slash

i've updated my htaccess file and my rewrites are getting this accomplished:

for example this:
http://ikonltd.com/current/
and this:
http://ikonltd.com/current
both go to the same page

here's my rewrite rule for that:

RewriteRule ^/current/([^\/\.]+)/?$ /current/index.cfm?PageNum_curreximages=$1 [QSA]

works great.

for some reason my rewrite for this URL is different:

http://ikonltd.com/new/

and this:
http://ikonltd.com/new

does not work.

here's my rewrite for that:

RewriteRule ^/new/([^\/\.]+)/?$ /newaq/index.cfm?PageNum_newaqimages=$1 [QSA]
RewriteRule ^/new/(.*) /newaq/$1 [QSA]

it has something to do with this last bit:
RewriteRule ^/new/(.*) /newaq/$1 [QSA] (which i'm not using anywhere else in my htaccess - just for the newaq section.

you'd think if i deleted it and just used this:
RewriteRule ^/new/([^\/\.]+)/?$ /newaq/index.cfm?PageNum_newaqimages=$1 [QSA]

it'd work but it does not.

again - i need both of these urls to resolve to the same page:
http://ikonltd.com/new/
http://ikonltd.com/new
