I dont know what i am talking about so take this with a grain of salt..... But the shocks used with the "A" style use a smaller spring and smaller bolts to attach to the the frame and swing arm. Now the engineer in me says that this would indicate that the stresses involved in the "A" style would be lower than the mono style swing arm. Less stress would be a good thing from a design point of view for any piece of machinery. As to handling and looks and I will leave that to people who know what they are talking about.
