Back in the day I really enjoyed Foggy and Whits racing styles and I could talk to Jim Whitham for ages without getting bored, I like his sense of humour, so I have a slightly biased opinion. This DVD is mildly amusing!
If you are/were a fan of these two, then get this to add to the shelf. It is somewhat entertaining watching the action and listening to Jim, however Carl is, quite clearly, purely a racer and it is easy to see why Jim is currently all over tv coverage of road bike racing.
Bare in mind, there are plenty of tv shows that have all this 'crash/saved it' action in them and you can listen to Jims wisdom-flooded commentary most weekends throughout the warmer months. So what you must consider is - are you going to be entertained by this and do you really need educating about racing lines and braking points. If you do then may I suggest you do a few track days and an advanced rider course before you even think about going out on the road, you really should already know this stuff!
