I bought an expensive thule one to get my bike from France to Ireland, went for the one that clamps on the fork as it was like 12 hours driving at 90mph and I was terrified of carbon cracking.
It didn’t, bike was fine so if it can cope with that it’ll cope with anything I reckon
Also roof vs rear mounts - roof racks will take heavier mtbs easier and more securely than strap mounted on the rear, reckon I’d want a proper towbar rack to move a big dh bike on the back
Christ this is dull even for bw chat
