Littmann master vs STC

by Nvision Nvision (New) New

Hello, I purchased the master cardiology and would like to know if anyone is familiar with using both the master and stc models. I understand that if you work with peds alote having a stc would benifit one since the bell is smaller. Just need to know two things:1. Does the master's scope peds adapter have the same or better quality as the out of the box stc scope?2. When working with non peds why would one choose master over stc?
