The .177 will run much smoother at 10.5. Lose half a coil and try again, repeat if necessary.

As the man says above, just shortening the existing spring slightly may well have the desired effect.
I have a WonkyDonky kit in one of my 99s and it's lovely. You could approach him and see if he has a spring. I could well be tempted to ask him for a .22 spring, sacrificing power for the even milder cycle that you are after, although some would say that it may drop the power too low. Worth a try in my opinion and you could add a little preload if the output was too low.
If you have the spring out of the gun at present, you could check its measurements against some of those stated on the Mainspring Data Thread in the Useful Tips section.
If choosing a new spring, don't forget you'll need to make sure that the guide (and top hat if desired) fit properly.

Thanks all for the advice. A thought: would collapsing a coil have the smoothing effect on shooting characteristics I'm after?
It seems that this would be the equivalent of shortening the spring and adding some preload washers, and wouldn't involve having to refinish the spring end. If it wasn't beneficial I could then remove the collapsed coil and refinish the end to achieve the shortened spring situation.

I run mine with a longer, softer spring. Nicer, softer firing cycle, easier cocking, and less piston bounce.. power is actually unchanged at just over 11 (in .177)
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
I remember talking to Shauny about this and he finds a Titan meteor spring (cant remember the number), works well in these. Probably need a piston sleeve as likely be of smaller diameter.
