How easy are the 600 to start? Looking at a '13 RMK for the wife and trying to decide if the ES is worth it or even needed. She is no weakling but i can maybe see after a long day of riding it'd be nice just turning a key. However, if they are pretty easy to pull, I'd prefer not having to deal with another battery. What do the ladies prefer or what do the gents have for their better halfs? 
Thanks,
