Using my bike with GX Eagle on it much more now. Other bike is 3x9 Shimano XT. One thing I've noticed with GX is mine can't 'panic shift'. i.e. you suddenly want to drop a load of gears at once.

On the other bike you can get from the middle of the cassette to the largest quickly as long as you have a bit of forward momentum and you ease off the pedals a bit.

With GX something seems to give up - shifter moves but the mech stays where it is. But then all works as normal once you get going again.

Do SRAM shifters have some sort of protection built in or something??

I don't tend to dump a lot of years as you describe to be honest as it offends my mechanical sensibilities.lol

The thing is, with the gx cassette, going from middle to bottom in one hit is a massive tooth change and I guess it's asking a lot of the mech.

That said, has the mech got a lot of play in it??

lol, agreed!. But now and again you get caught out and Shimano lets me get away with it. No, no mech play at all.

Happened a couple of times yesterday. Mech doesn't even move, shifter goes light - as if the shifter is saying 'not doing that' and lets go of the cable temporarily to save itself from my ham-fisted shifting. Just wondered if it was a feature?

Eagle is different to ride, isn't it? Bit like going from normal gearbox to sequential.

That rings a bell!

Have a look for a recent thread about the gx.... A lbs owner on here mentioned seeing shifters with the cable sliding in some way inside that it shouldn't be doing.

Sorry to be so vague.

I have just had to rebuild my shifter and no sort of protection voodoo inside sad to repor.

Sounds like something in your drive train isn't playing ball.

Hmmm. Speedy, fairly flat ride today and all worked fine, so seems to be when you put the shifter under load. Will keep an eye on it...
