I did the Wilbers shock 3 years ago and it made a huge difference in comfort, plus it kept the original rear Metzeler rim protector in contact with the bumpy pavement around here. When a fresh set of Road 5’s became available, my mechanic mounted them and replaced the fork springs with Wilbers units. I went with Bel-Ray 7 wt. (cSt 29) to replace the Honda 10 wt. (cSt 35). Might go 5 wt. next time. Conveniently, it took exactly 500ml in each fork tube to set the air gap at the prescribed 130mm. Front end feels better controlled but only a moderate change as compared to the tires and shock. All told, it’s a whole new bike. Comfortable and handles great. I’m 5’5” and 150 lbs.
