I was in the same boat a while back but decided on a well spec'd 4/4 rather than the sport. It has a spare wheel for starters which I prefer and a host of extras which are not available, at present, on the sport. You should be able to find one that's almost bespoke for you.
Not knocking the sport, just not my 'cup of tea'. It's your shout. Have a good look at all your options before you part with your money.
Cheers
