Vela, Together We Await The Storm intro and chorus arpeggios

[LEHUSKEH]

Has anybody tried or nailed this song by The Human Abstract before? The difficult part for me are those wide stretch arpeggios that they employ at the mentioned song sections. Sweep picking for my right hand isn't a problem for me but my pink is kinda short and it's hard to hammer on at the 10th fret and pull off cleanly to the 5th fret, resulting in some unknown string ringing out despite the fact that my palm is planted on all the strings to mute out any unwanted noise. Even with my thumb way below the centre of neck, its still difficult for me to execute it quickly and accurately.

Does anyone have any alternatives, or must I have really big hands to pull these wide stretch arps off?

Thanks and cheers
