Chuck,
The only use of the linesman glove was to put the HT anode lead somewhere that would hold it from moving, and to keep it away from me. I never implied to wear them while working in electronics, they also have a leather shell glove to protect the linesman glove from damage.
But I do use latex gloves when doing this work, I'm not relying on them to protect me, but rather to add a weak safety net, since I have them lying around, they improve grip, and add a decent layer of uncertified protection, but they tear easily.
This reply is a little dated I know, haven't been following the thread for awhile.
