I think the old thicker razor blades would make an Old Type more aggressive, not less aggressive -- it's less aggressive with modern thin blades. This is because a thicker blade lifts the edge away from the cap (the base plate). Some people shim the Old Type to make it more aggressive. With Astra SPs, Old Types feel to me about the same as a Fat Boy dialed to 5.
