Thank you everyone. I have been 'twizzling' for years - but the problem, now that I'm getting a bit rheumatic, is not putting it on, but undoing the damned thing to get it off (though i must admit i haven't tried twizzling to undo it - perhaps i should). Many, many years ago, it was quite easy to get a front loader, but no more. However, thank you jo1book, i will look for Isla & Angelcitiz on Ebay - after all this time researching, 2 weeks wont be too long to wait.
Interesting how the subject has turned to hi-viz underwear though - now there's a thought!
