I get it. But the shaft wood and other components and materials were quite different as well. Do you have a Cobra Pro? They have not been made for a long time.
The most recent similar in quality cues were the Sierra models, and before that the GW Collection, although most of those were crap, some of them were of good quality. Many cues were made with various branding and various quality levels over the years.
Specifically regarding the two Cobra 525 Side Winder cues you have which were branded many ways over the years, a few of them were of the Cobra Pro quality, but most not. That model was never produced in the Cobra Pro model line. They were variously branded:
1) Craftmaster
2) Cobra
3) Competition
4) Slyfoxx
5) GW Collection
6) Pinnacle
7) Sierra
8) Crystal Leisure
9) Unbranded
