There are a couple other key metrics on this report you'll want to look at when optimizing these keyword phrases.
An indication of the effectiveness of your landing page is measured by the bounce rate - the percentage of visitors who land on your landing page and then exit without going any further into the site. The bounce rates associated with your "short head" keyword phrases should be the lowest values on your report.
And, if you're an Ecommerce site, you'll want to pay close attention to your return on ad spend (ROAS = Revenue/click costs). This metric is a more accurate reflection of the profitability of your keyword phrases than CPA because it also takes into account the revenue generated from those keyword phrases.
A combined approach of appropriately managing the "short head" and the "long tail" of your accounts is obviously a sound strategy. Allocate your time and testing resources based on the potential return. Be sure not to get carried away by the seemingly endless possibilities of the "long tail" at the expense of your highest spending "short head" keyword phrases.
