I worked many hours in Sainsbury's, mainly Saturdays, when I was at school to buy a Holdsworth Cyclone (1966 model still current in 1967) The only bike I've ridden more comfortable than that was a 1969 Holdsworth Mistral. That bike did TTs, touring, commuting, and anything else I asked it to. Give me the person who stole it and I'll be spending some time being looked after at Her Majesty's expense...
The bike you've bought FF is from a later era of the company but they were still very fine bikes.
You nearly didn't get that bike, but I was informed that if I wanted it I had to sell my Dawes Horizon, and I was still considering the matter when you jumped in and bought it!
Enjoy it. It looks the part and from your description it's a bike that just wants to be ridden.
