I feel like goldilocks. I started, bought and then returned a GST- it felt too boxy and awkward. Then I looked at loads of PSTs but too small. Now I have tried the XL and think this could be it- spacious and longer. I like big bags. But what do you think ladies? Was I too rash moving away from the GST? Will the XL be too big and what about weight? Too heavy? XL users I'd love your opinion. Thank you x
