Running Dynamics - Advice requested

Hello everyone,,

Been running for approximately six month and seen some great improvements and training for my first 10k next month.

I am interested in learning more about my running Dynamics and debating between the running pod or a strap. It seems the HRM-Run has the same things as the pod but also has a stronger and more accurate HRM than say my FR645.

Is that about it? Does anyone have any first hand expertise or advice they'd like to share?
