I can't give a comparison between a finderscope vs larger scope for guiding as I have only ever used the finderscope. I've also only regularly guided focal lengths up to 640mm.

Everything works with ease using my TS115/800 and reducer though I'm sure more care would be needed with long focal lengths.

My finder/guide scope only needs to be approximately in line with the main scope and the polar alignment routine built into the mount is plenty accurate for my needs.

I did shift the finder scope into a more rigid mount, though I never had any issues with the first setup.
