Pros\Cons of using Custom Tags ???

[Devesh H Rao]

Hi everybody,
I am working on a project which is extensivly using custom tags to do the presentation logic on the JSP's . I wanted to know about the cons of using Custom Tags (we are at present having about 6-7 tags per JSP).
Other than making maintainence of the pages easier and making the painting logic standardised are there any other pro's for using custom tags.
Thanking u all in advance
