Looking to replace an old hard side case for diving travel. Last trip was impossibly tight, so I think I decided I wanted to switch to a wheeled duffle for my next trip. I carry all electronics and regs in my carry on backpack, but on my next trip I will be taking additional drysuit, second pair of fins, maybe 2 wings. So it's a lot. Curious if anyone has experience with Osprey Transporter bags and what their thoughts are between the 90 or 120... I guess for only $20 more I should just go for the bigger one but love SB's opinions.
