Ok, I know there are other threads like this out there, but now I need help. I want to get my 1st Speedy & I love the new Azur line (saw it IRL Saturday!). I have to call NM asap to order one before the price increase but I cannot decide between the 25 or 30. I'm 5'7" so I'm leaning towards the 30, but the 25 is cute too. What to do...suggestions please??
