300/4L IS?

[ed.]

So I've got this lens, should I sell it for a 70-200/2.8?
Or attempt to use it and see how I go?
I've got a 24-70L which I use already but just wondering if anyone else uses a 300/4L IS for weddings :p

The 300 F4 would be great if you wanted to take photos from way at the back of a well lit church... or perhaps if you were a wedding stalker. For real weddings... 70-200 for sure :)
