I need to bend a mix of 8mm and 10mm copper pipe, I see that one can
get pipe bending springs for this (that seem to go outside the pipe)
and also simple pipe benders like this:-

Which should I go for? Currently I'm tempted to go for the tool (or
one like it) rather than the spring(s).

Any comments?

A 6/8/10 bender at £10 would be preferable to any spring.
