32" arrow and 29" draw. That got my attention too. [:-] I have a 33.5" draw on my compound and shoot 32.5" arrows.

Oh well... Answer to your question is, the extra half inch won't affect anything. That's assuming the 32" arrows you've been using aren't on the raw edge of their spine range.

But I would suggest for you to visit a different pro shop and see what they say about your arrow length because something is very screwy somewhere.
