Thank you!

The Newton is a good fall protection harness if you don't need the chest ascender or lateral (side) D-Rings.

I would recommend the Astro because it includes the built in chest ascender (Croll). The Avao is no longer offered with the chest ascender.

@@RooftopSafetyUSA why not just use two hand ascenders

The descenders and ascenders allow you to make progress on steeper slopes that are not easy or safe to walk on. Sternal D-Rings are used for fall prevention on easily walkable slopes.

@@RooftopSafetyUSA right right near the edges on easy walks I would use the back shoulder ring on what pitches would you use the sternal

@@Brandon-no3vc I would use the sternly D Ring for fall protection on easily walkable roofs, like under 6/12.

@@RooftopSafetyUSA so 6 12 and under use the sternal ring and anything over use the central waist ring unless working near edges use the back shoulder ring?

Which two harnesses are you referring to?

​​​​@@RooftopSafetyUSA avao and the petzl astro. The 2 harnesses on this channel.. what do you mean what do I mean

@@redsresearch the Astro is the current version and replaced the Avao with built-in croll chest ascender. That model was discontinued when the Astro was released. They are very similar but the Astro has a few improved features (more padding, releasable left-side shoulder buckle, Croll ascender with wider opening).
