Hi,

As I recall, general wisdom in ARSC suggests that 
for archives the use of NO leader tape at all has 
always been recommended for tapes to be stored, 
since attaching leader(s) involves the use of 
splicing tape, another material to be avoided as 
much as possible. Obviously one must deal with 
splices that come in on tapes; but except for 
attaching leader or blank tape temporarily to 
allow capture of beginnings and endings on 
recordings lacking sufficient unrecorded "slack", why ask for trouble ?
