WTB: lightweight 1 or 2-person tent or tarptent

I am looking for a lightweight (preferably less than 2 pounds, but will consider >3 pound) tent or tarptent for trip at end of August. Very good or excellent condition.
I have a Big Agnes Seedhouse SL3 but don't want that much room for one person on this trip.
I have a SilShelter 2 but want more coverage (weather may be nasty).
I was very fortunate to find a Big Agnes Fly Creek 2 on this forum at couple of years ago ($180) but gave it to my daughter and she is taking it around the world so I won't see it again for a while.

I will be hiking with adjustable trekking poles. Any offers?

Thanks.
