However, if you don't have that, nor suffer from overheating, pointless IMO. And shocking to see it on a fellow grey rst

exactly, when do you know if your bonnet catch will go faulty? as it seems to be common on rs's
raisers ive put on jus to release heat, cant see anything worng with that other than it will get rid of heat quicker than if the bonnet was fully closed
