Which cantilever to choose for re-tip


I have two cartridges I plan on having re tipped by Soundsmith. One is a Shelter 501 II, and the other is a Lyra Lydian B.
Both of these came originally with boron cantilevers. 
Is it worth the $450 each for the boron or should I go for the $350 ruby?

Why not call Ledermann and ask him about it? The carts are different enough could be one is more suited to one than the other. If anyone would know it would be him.
