I’ve not used the Flywheel tool but I have one of his Clutch holding tools which worked brilliantly as it locates against the ground allowing you to give maximum effort to undo the nut.
Using my ‘man maths’ I worked out that the combined cost of the holding tool plus mains powered impact gun was cheaper than a shop doing the job, equaling the satisfaction of doing it myself combined with getting more tools!
