Having put together pages on PBase, Zenfolio and Smugmug, I emailed my friendly sports desk edtor to ask for his opinion, as he's a pro at this kid of thing...
Thought I would share it back for reference:
Hi Mike,
Good snaps again!
I've just had a look at all three sites and I think the smugmug looks the most professional and is easy to use. It's also pretty fast to bring up a full-size pic, although I thought the zenfolio site was the quickest to use, but I wasn't overly keen on the website lay-out.
Pbase is also easy to use but smugmug was my favourite.
Hope that helps,
Steve
So thanks to the flickr voucher code 
I now have a paid up pro account on smugmug.
'Nuff said.
