I would ignore the pack-size – just put it in a stuff-sack and squish it down lots – you will probably end up reducing the amount of space by 50% (I did with my laser comp anyway).
I reckon most people would rate the laser-comp over the Vango, but they might just be brand-snobs.
Probably not much difference between them to be honest, the laser-comp is a bit lighter but I doubt you would notice is.
On another note, doesn’t the laser-comp compare more to the Helium 100, and the laser to the Helium 200?
I’ll be out in the lake district next week in my laser-comp. Weather looks like it’s going to be pants, so hopefully I won’t drown during my sleep 🙂
