Cheers man. Yeah I was super-impressed with the durability of my old Vango, 20 years for a tent that was about £80 at the time, lots of wear and tear but never had a pole snap.
Alpkit bags look a bit pricey for me. I've been using a Mountain Equipment (dragon something or other??) that was £40 a decade ago and that seems fine. Will look further, not as urgent as tent.
