I still remember half the riders shitting themselves at how mental/difficult the track was the first time an NPS was held at innerleithen (’95?), it wasn’t realy anything too difficult/gnarly back then, the track is still pretty much intact (albeit a little blown out in places) and would be considered pretty tame by todays standards, it is indeed still regularly minced down on XC bikes without them breaking.
I actually oved Zaskars but happened to know a few riders who cracked them, they weren’t racing DH on them tho. 😉 later on LTSs were way worse for cracking.
