Its all personal - but a very general rule of thumb is you can go 10lbs heavier on a traditional bow (this was on a english longbow page) compared to a recurve due to the change in styles used.
Personally I went from a 38lb recurve to a 50lb longbow - I could barely string it to start with and now a month later its no problem at all to use - but everyone is different.
(In fact since then I have upped my recurrve limbs to 42lbs as it just felt so light after the longbow!)

Using that very loose rule either should be ok - 32 + 10 is 42 so 40-45 should be no problem.
However - since an AFB is actually very similar to a recurve - I suggest waiting until someone familiar with those bows comes along to advise on it.

But I personally would go for the 45lb.
But thats me.

EDIT:
Isn't it always the way, as soon as you hit the button you think of something you should have added!!

Which ever you go for - take it easy - what ever weight you go for always remember that its a big jump in weight to what your back and shoulders are used to. The last thing you want to do is cause yourself an injury and be unable to shoot for a while - so take it out shoot a few ends and dont push yourself - if you start straining then stop until next time.

Whatever you decide to go for I hope you enjoy it, and do wait for a reply from someone more experienced with AFBs - I may have gotten it all wrong lol
