>> Pyramid so they have steep walls. Flat felled seams.
What are the type of seams between the 4 sides of an MLD pyramid ? Wondering how much I need to worry about seam-sealing.
Duh, taking a few seconds to look at MLD's page (for my SpeedMid), it says: "Main seams are triple rolled and stitched (MLD Exclusive) and flat felled".
I have had it in one reasonable (in intensity) but brief (15 minutes) rainstorm, and no sign of leakage (before doing any sealing). Now, I have sealed some, on the inside - since that's how I've always done older regular nylon tents in the past - but now I see people here tend to favor outside. Oh well.
