My drones and regs are by Charles Roberts (and I couldn't be happier with the drones, which have a lovely "ping" to them), and I play a chanter by Tony Hebdon. Everything seems to balance well enough (although it's taken some tinkering), and the Hebdon chanter is much better in tune than the original Roberts one was.
I think it's great that you can "hybridize" the pipes--on most instruments, you don't have any options that way!
