Discus 2b versus LS-6c

To me, big questions are.....
Where do you normally fly?
What is the aircraft mission (contests, XC, thermals, ridge, etc.)
Do you plan to go to other places to fly?
What have you flown before?
What did you like/dislike about them?
Are you a larger pilot, smaller pilot, or in between?

A sailplane that is good for one pilot in one location may not be as good for a different location.

Beyond that, I have not flown either ship but have flown against them. They can do well.
