Dukes are functional but not top of the line. Were there any magnum body grippers 20 years ago? There are number available today. The market is forcing inovation through competition. As far as coilsprings go, check out the MBs, they have set the bar high.
What's a 'magnum'?
Back in the day we just had 110s, 120s, 220s and 330s.
Glad to hear things are progressing.
