Weight weenie bike on a budget, this should be interesting

From an acceleration point of view rotating mass is important. From a climbing point of view, unless you are a "pure" climber like Pantani there is no difference between 'rotational' and 'real' weight. Your 1500g wheel will feel like 1500g at a constant climbing speed.

Pantani? I fucking cycle to the pub on the other end of town and back.
