One of the hardest FH's off all time? - Practice points vs Robin Soderling (Former ATP #4)

Some highlights from when I played some practice points vs Robin Soderling last year!

What do you guys think, is he up there with Del Potro, Roger Federer, Alcataz, Gonzalez, Safin as one of the hardest/heaviest hitters of all time? He's certainly up there for the people I've played against so far haha...
