Yes BC have changed their supplier from Contour to Pomoca this year.
But i guess Solis skins should continue to be sold with the specific hook (it's the only model with this cutout). Pics on website...

I bought my Solis one year ago on the BC website, and skins have been delivered with the specific hook fitting the tip cutout.

Skins sold for the Solis are equipped with a special hook fitting this cuttout.

Solis are not light but definitely not heavy. Mount them with ATK R12 or FR14 and it's a real good combo for steep....
