Yeah, I really like them both! Backwoods geometry does look quite different when they're side by side! Also, Backwoods bottom tube has a significantly larger diameter, almost the same as Zaskar! Would be interesting to see Avalanche and Backwoods side by side!
Backwoods are pretty cheap, just picked up a complete '97 spec for 40 quid! Try getting Zaskar for that with a similar spec? You wouldn't even buy the frame for that! Zaskar is commanding way too much wonga imo! Especially as I've just picked up a rough Richter for 20 quid, complete bike, albeit not original but still complete!
