Nice, Nimbus has a good reputation for support, fits the long, narrow foot types, and although the shoe is a bit bulky for shorter distances, the discount helps. How long and often are you planning to run? I trained triathlon and marathons for a long time and always had a couple different shoes to play with. The Nimbus is a great big distance shoe for your foot type - are you training long? Might be fun to have a second lighter weight pair (e.g. Cumulus) for shorter distances, e.g. less than 4-5 miles.
Also, strike and stride are personal. If you want to train yourself to strike flatter, do it, but I would be cautious about transitioning to 'barefoot' running, as it requires considerable retraining. Yes, it's more natural, however, it doesn't make it better for your current technique without practice.
