I agree with most of that/don't know enough at this early stage to form an opinion, however there are a few tweaks I'd like to make to some sports.
Athletics - Under this new regime, I don't expect any athletes to get in via world rankings. Reynold Banigo is one to watch for Men's Long Jump, he's in fine form.
Football - I think you're unfairly writing off the U21's, they have the quality to get the quota for the men.
Shooting - I reckon we can qualify as many as 10, we look in good nick in the rankings in most events.
Swimming - We should send a full quota of relays this time round (yes, that includes you Women's 4x200m free relay). Half the women you included in the 100m + 200m free section will only do relays, Hopkin, Hope and Anderson will be the only individual competitors in those events. Holly Hibbott is more of a 400m swimmer than 200m, so she'll go for that and be entered into the 200m relay (met her at a local swimming comp about 5 years ago, lovely person). I can also see Greg Butler qualifying for the men's 200m breastroke. Shame we don't have anyone good in the women's 800m + 1500m free to complete a full set of quotas.
