You would have to work out what spring rating you needed and then get one specially made. Somebody on here did that once!
Can't remember which ones are softer, but seem to remember if you fit a late Mille shock, (yellow spring), with the standard Falco dog bones it ends up much too soft ( :smt017 )
So yes it is usually much easier to use the appropriate dogbones.
True - but having different leverage to that for which the shock was designed will change the stroke (even with the spring and valves changed).
If the stroke is similar that's probably not an issue but if very different, maybe the replacement wouldn't have enough movement for the suspension or maybe the movement would be too little to use the shock that effectively.
I don't think it's likely to be a big problem with the shocks discussed (though I don't know for certain) _ I think Mangocrazy had one revalved and resprung and he reports it worked well.
Best solution is to use a shock as it was designed to be used and for the early shaped Mille kit, best to use shock with the linkages it was designed for ... works well on a Falco.

Yes - 'twas I (and I think Paganman did as well). The generally accepted wisdom is that you use the triangles and dogbones that match your shock. In most cases this will be RSV Mille Sachs or Ohlins and matching triangles/dogbone.

The reason I used an RSV Mille Ohlins, Falco triangles/dogbones and non-standard spring was because the RSV Mille dogbones fouled my Falco hugger (that I'd just had painted at great expense). The Falco ones didn't, so I replaced the Ohlins spring with one that had the same effective rate as that fitted to the standard Falco shock (800lbs if memory serves), and used standard Falco triangles/dogbone.

It's another option that's available, that's all. I doubt it's any better or any worse than the RSV Mille shock/triangles/dogbone option.

But my hugger is intact. So that's alright then...

Standard Falco (and early RSV Mille) spring rate is 800lb/in (or thereabouts), RSV Mille (up to 2003) spring rate is 540lb/in or thereabouts, so you will notice the difference if you fit the 'wrong' spring.
