The Cirrus that was 'basically an fiberglas SHK' was the open cirrus. Not the standard. Same name Whole 'nother Bird.

Not really though. The(Open)Cirrus was a very different sailplane, with only the V tail on the prototype being similar. The Open Cirrus had a Wortman airfoil, not an Eppler that was used on the SHK. Also, different wing, very different fus shape, along with the more modern composite construction using glass and foam.
