Ikon rear shocks

Gents,
Time to replace (original) shockies on the '77, Z1000, got into corner little bit hot and I struggled when the rear started wallowing. Looking at Ikon 7610 series, price seems ok, any experience out there with them?

I've got original Koni 7610's on my old Yamaha. They do the trick, Adjustable and feel good. Plus they're rebuildable.
You can buy different weighted springs from Ikon too.

Thanks SteveW, have just ordered, lets see if the old Zed improves!!!
