i agree with the above --the mulit licensed high level lame's at line maintenance are the reason's why the company thinks lame's are so expensive- but what they fail to understand is their grading system is all ready taking effect. most lame's ,young guy's comming through will only gain one to two type rating's in the future -then they will only go up on service point's it will be a long and slow process.
lv4 and lv5 will make up the majority of lame's at qf in the future -with snr lame's and acting sr lame's holding every type and remaining at top.
