Huh?  We have used 35S with good results in cycle sequencing, but there
is a problem with "shadow" bands that in some instances make it
difficult to decide which base comes next when you read the autorad. 
My res. asst recently directly compared Sequenase with cycle sequencing
using the same primers, source of DNA, label, etc, and we got much
nicer and easier to read sequence from the Sequenase reaction.
