cost a fair bit of performance.

not on the 1-26. You cant do anything to them to make them perform
worse

I have proven to myself over many flights that opening the spoilers will
make them perform worse.

As for more subtle changes, you might be surprised. My friend who's
letting me fly his keeps talking about moving his oxygen bottle, currently
in the nose, to behind the seat in order to move the CG back and gain a
bit of performance. Personally I'm kind of doubtful about this strategy
but I guess it shows that 1-26ers can worry about performance too.
