Incidentally, the fibreglass in these frames was "S2" fibreglass - supposedly stronger. Does anyone have any info on "S2"?
An excellent way to develop a line of rackets, IMO. Back in the '70s through '90s, quite a few companies took advantage of this techinque...allowing some interchangeability of bumpers/grommets, etc. Head, Wimbledon, Wilson, Chris and others had a 'progression' of materials, stiffness, price throughout their lines while using the same mold for the various layups. It was very common when a brand wanted to offer SMUs to large retailers...same mold, different cosmetics and sometimes, different compositions. Brilliant in its simplicity.

Here's just an intro on S2 fiberglass:

"S-2 GlassŪ Fiber Family of products offer a combination of six vital enhanced properties critical for your demanding applications. Compared to conventional glass fiber, the ehnanced properties of S-2 GlassŪ fibers result in better weight performance, and when compared to aramid and carbon, they deliver better cost performance."

There's an eighteen page brochure...IF you are trying to fall asleep!
