i just thought of another way to characterise it compared to my carbn and my steel.

imagine you are lying on a bed and it is being jolted under you. steel would be like a plank of wood so every jolt you feel directly. Ti would be like a water matress so you feel every jolt but it is more like a push than a hit. carbon is like being on a foam matress where the smaller jolts might just be soaked up by the matress and you don't even feel it.

i don't know about aluminium. maybe like a baseball bat smacking you?
