NEWBIE: Exception on 'of every'

I was experimenting with a small bit of code:-

tell application "Font Book"
	set enabled of every font collection to 0
	set enabled of font collection "Web" to 1
end tell

This works perfectly, however is there a better way of doing this? I.E. set every font collection with the exception of… so it doesn’t disable “Web” and then have to re-enable.

I hope this makes sense. And thank you for your time
