Well, being on the Morich area of the site, I would think most here would encourage Morich equipment. However, for heavy oil the GP2 is the best of these 3. I see on the Track area you threw in the Angular. Clearly the least hooking of the 4. I have not thrown the WMB but have seen it thrown and it will handle med heavy but the GP2 will handle the true heavy heavy.
