I posted photos from my old tractor. I now use a Kioti DK40se with a loader lift capacity of 2700+lbs and use the same grapple. I've never wished I had bigger and the 48 inch light duty grapple has done all I've asked.
One other advantage of the narrow grapple is when digging roots you are putting your breakout force into a smaller area and hence put more on the roots or rock you are interested in and don't waste a lot of the force on irrelevent ground on either side.
Here are a few photos from the new tractor plus same grapple:
