Fully agree re running the maths rather than relying on good old trial and error. Most can't / won't / are hesitant to try (myself included), but it really would be the way forward. But at least these days there is a decent knowledge pool to dip into.
So, horticultural uses of mainsprings isn't a market cornered solely by the Ox?

A good starting point for tuning any springer, is knowing what you want to achieve.
If the goal is a snappy, harsh, and hold sensitive rifle, the Titan is the right choice of spring.

Fully agree on the first point, Rob.
However, re the Titan springs, many have enjoyed excellent results using Titan springs, more often than not when choosing a thinner wired option intended for a different model. I have very little first hand experience of them myself, but people like Welsh Willy certainly makes them work in his kits and NickG often successfully uses Titans in his tunes, even some of the narrow bore conversions.

I meant that particular spring that the OP has used. He's gone far enough down the rabbit hole to realise its not suitable.
But I'm no fan of the brand in general.
OK for running a full fat, 80 or 52, but not my preference for sub12.

Is there a reliable online source for springs which are softer/thinner gauge than HW factory spec?
Perhaps we need more springs branded as 'Sylvanian family' rather than THE TYRANNOSAUR PISTON SMASHER 9000?
Good deals with these members
Thank you Tony, I'd forgotten about that resource, very handy for cross referencing.
It would however still be nice to find a supplier of generic springs (not necessarily 'airgun' springs) listed by spec, in case there isn't an off-the-shelf spring for another rifle that corresponds to the one desired.

Our scribbles say your spring should be 235 x 20 x 3 x 29 coil x 34 lb/inch rate
Titan 8 297 x 40 lb/inch. Cutting coils, as said is going the wrong way.
The new 10+ could be a match.
Excellent info, sir.

Once or twice in the past I have done Google searches for spring suppliers and there are plenty to go at. Some suitable for our uses may be available off the shelf, although I guess we'd be very lucky if that were to be the case.
Jim Tyler mentioned on a recent-ish thread that Dr Mike Wright and he once had a batch made up to their specification. I seem to remember that the minimum order number may have been 20 springs or so to make it a cost effective exercise.

Thanks for the replies guys, perhaps I have misunderstood these analogies?...but cocking effort is not a consideration for me at this stage.
Thanks Max, the original spring is S shaped, crunchy on cocking and produces 6.5fpe.
Thanks again BTDT, please don't think I'm bloody minded (although I am ) but I am going to carry on with this experiment to find out for myself as I have nothing to loose and the experience to gain in doing so ...but I will be ordering a more suitable spring too.
