I still don't get the difference between my version and your first method /:

Why should I use that one instead of mine?

The second one is really interesting, I'm not very familiar with custom filters, I guess I'll be looking into those soon ^^

 

Thanks

Cleaner, easier to understand, not making un-needed objects. etc.

The second method is cooler, but keep in mind it's more resource heavy.
