ummmm its kinda noticable. put it this way when i was changing my tires i pick up the front wheel with the deep v on it and the rear has an open pro. it was noticable that the deep v was heavier and it was the front wheel without a cog on it. so its nothing really too serious tho but noticable. the trade off for the weight is a stronger wheel tho plus asthetics which is kinda nice but then again i just put my foot in my mouth cuz im complainin about a couple oz. what a wuss i am lol.
