Observing Book format

Hi all,

I have a survey type of question. Should I offer the hardback version of my observing guides? I will continue to offer the coil bound version that is popular among observers. There is a small price difference though, about $4-5 more for the hardback. Same high quality 80# paper and print quality.

Alvin,
I prefer the coil bound just because it is easier to use at the scope.
Thank you for all your guides.

I agree with Mark, much easier and probably more durable.
Again, thanks for the helpful guides!
Al

Another vote for coil-binding!

I vote for Coil-binding also.
