ok fellow 200G fanatics... any idea what causes these frames to warp??
just noticed my black-grip example to have taken a kink at top of hoop.
No frame cracks found, strings measured as evenly tensioned all round ok.
My green-grip Grafil (bought & owned new) has survived school
& left in hot cars etc yet still stays straight at the beam.
Worth clamping in a vice & torsioning it back?
