Compact Double - Grip Shift Triple Comparison

I have decided to purchase a Specialized Roubaix Elite, but I need to figure out if I need compact double or triple...

The only comparison I have is what I currently ride. A 2002 Trek 7500 Hybrid with Grip Shifts and a triple.

I live in an area of rolling hills, you can view the elevations of some of my rides at the following site...

On the most difficult hill I an encounter I find myself using 1-4 (Grift Shift Terminology). What would be the comparable gear for a compact double?? Is there a simple explanation as to this gear=that gear?

I am still a noob so I don't quite understand the numbers thing in regards to gears and such. All I know is that the Roubaix compact has a "11-28" as its smallest gear.

FYI I am a clyde weighing in at 260lbs if thats a major factor.

What advise do you guys have as to compact vs. triple?

Added Question. Would it be easy to convert the compact double to a triple?? The components are 10 speed 105s by the way.

Thanks in advance.
