The <68 type on mine uses the rods which yours won’t use. However the triumph forms which yours should have work really well when built properly.
Kommando knows a lot about shocks so I wouldn’t take anything he says with a pinch of salt, with mine I just rebuilt everything with a keen eye. The progressive fork springs were a good buy in my opinion and I think help with the varied deflection high and low. But as long as you have them so they are pretty smooth on the road, the rest is down to riding, it’ll never handle like a modern bike but that’s most of the fun.
