I have a friend who works for a large spring manufacturer here in my city.

We got to discusing MONO LEAF transverse springs and he cautions AGAINST using them. His shop has replaced several of them.

He feels a MULTI LEAF spring can hold together if the main leaf breaks.

He admits they ride softer, BUT if it breaks it could cause sever damage. I currently have one under my '28 A Tudor Hiboy - flathead powered.

Anyone here have one of them break??
