I need to make about 30 cuts in 3/4" water pipe
while hanging 40 feet in the air.
I'm thinking the reciprocating saw will be too heavy
and hard to handle, so I'll try with a jigsaw.

What do you recommend for saw blades?
Teeth per inch?
I'm looking for a compromise between speed of cut
and blade life. Changing blades won't be easy up there.

Home depot has a whole wall of blades, but I'm thinking
that buying the most expensive may not be the optimum choice?
Anything particular to look for?

Thanks, mike
