OK so i recently asked for advice for a road bike and had made up my mind only to find the model I wanted has been discontinued. So...of the bikes listed below which should I go for and why? Is there any other contenders that should be considered?

Specialized Allez Sport 18

Specialized Secteur Sport

Specialized Allez Triple 24
http://www.jejamescycles.co.uk/specialized-allez-triple-24-road-bike-black-charcoal-id65341.html

Pros, cons etc?

Please help - I really need to know which is the best

PS I will try before i buy but the bike store will need to order my size in as im so tall
Mtrlpqbi.. I'm not only looking at one store, I have looked at several and I'm not buying online either - how else am I supposed to share the spec of the bikes I'm considering without a link? I know a pricer bike by the same manufacturer is probably better but WHY and do i NEED it
