The main benefit of of dumping the nasty soft bendy plastic pins supplied in most of the volume-builders' instruments, and replacing them with denser, harder, stiffer material such as bone, FWI or brass, is in the better protection from damage to the bridge-plate. Even better is to slot the pin-holes and use non-slotted pins. The only plastic pins I use nowadays are 'Antique Acoustics' pins made by Willi Henkes of Blazer & Henkes (German builders of extremely high-quality guitars), which are made from a very dense, hard plastic and compare very favourably with bone in terms of density, hardness and sonic qualities.
