Nowadays, Rod1, I do very little business flying and in any case it is very hard to do that, in the UK where the vast majority of runways have no instrument approach and are "closed" in anything below OVC010 or so.
The ability to go IFR has a great deal of value for long distance touring. The fact that most IFR flights are done in VMC and sunshine doesn't detract from this (it just makes the IR training look way OTT). The most valuable thing that IFR gives you is an implied whole-route clearance i.e. a guaranteed transit of all airspace (that is available for airway traffic) and an instrument approach if you want it. The general ability to fly in IMC is very handy too but, assuming you can climb above the general cloud, it is not half as handy as the whole-route IFR clearance and access to all airspace classes.
The times I spent the most time in IMC was when boring holes in UK Class G cloud at 2400ft under the LTMA, on the IMC Rating
