I like the way Weyermann light and dark floor malt performs. I have used the malt since the time it has become available. In the mid 80's I used Budvar low modified, low protein floor malt which was very expensive and it too had the sweet, wet hay scent. The wet hay is a positive as far as I am concerned, it is part of the beer style and the malt that was used to make the beer, originally. However, some may find it offensive, olfactory systems differ. I think that the scent in the air coming off of a hay field after a rain is nice, others may get hay fever. The scent reminds me of summer and good times and the scent of a field during the fall, a type of melancholy sets in because summer is ending. Perhaps, a person has to live in an area where there are fields of hay and wheat growing to be able to tune into the whole thing and some have never had that option.
It is not a bad idea to use a malt data sheet and to learn what the data means. The sheet is produced for a reason and it is a valuable tool that a brew master uses. Many home brewers do not know of its existence.
