Not sure what the question is, as the Tectal, Kortal, A3, etc are all standard helmets that pretty much offer the same level as any other helmet, the Dropframe provides a little more coverage and weight, a bit like a chin guardless full facer, same with the Giro Tyrant and the Alpina Rootage.
Are you looking at other removable chin guard helmets, the ‘enduro’ style Dropframe/Tyrant/etc or just a normal lid?
Personally, i have 3 helmets, i have the Giro Montaro for all round stuff, the Dropframe for enduro stuff with uplifts or push ups, and the TLD DH helmet for those BPW days and the likes, i’m guessing you’re after the middle one?
