Do it! Thats all i can say, they are amazing tents.
Outwell are renowned for using 'too much' waterproofing on their fabrics - I have the Indiana 4 - it has withstood several severe weather bashings, never leaked or felt in the slightest bit unstable, even in the wind with it being so tall. Thats another thing - to be able to stand up in a tent when you get past 30 is a must!
The only down side to mine is that the pins that go into the bottom of the poles are really hard to get in but even so I can still set the tent up on my own in 15 mins.
I'll calm down now, promise... (you've just seen me in tent fetish mode - sorry, its very scary....)
