That would make sense as her regular gig is the small Belgian and French one day races so doing her homework on spotting riders at that level and their specialty abilities is what is professionally important whereas she does not get to cover the biggest races very often.Cheers. I didn't know that. I became aware of her a few years ago on the English commentary, and in that language she was definitely the innovator of trying to pronounce names/places as they would be in their native tongue. Which I liked, but also her speaking voice generally and the fact she doesn't feel the need to go bananas every five minutes. Plus she's more knowledgeable than most about races/riders at the lower levels, though oddly not about The WT.
In general I think at the level of knowledge some/most of us have on this forum, the English language commentators often don't add a great deal and can be annoying. So personal preference might simply come down to how much you like listening to them speaking?
