color profile -RGB98 or 'My Spyder profile'?

Hi there,

When choosing color space for CS2 & Aperture which should I choose.

My camera is set for Adobe RGB 1998 - which I believe is the standard.

I have recently calibrated my imac using colorvision Spyder2 - therefore I have created my own screen profile: lets call this 'My Spyder Profile'.

So it's an option in all the color space menu's. I am confused a little. I have chosen Adobe RGB 1998 (for now) but should I choose 'My Spyder Profile' ? if so, how does this effect my work with respect to my Camera files & any files I send to clients?

If Adobe 1998 is the correct space to work in, why do they give an option for your own color space?

any advice very much apprecited...

cheers
