can anyone help me make this decision? i have a wolfman duffel which works great but i was looking at the softbag 3. i had a softbag 2 i bought used which seemed like a great piece of kit but it leaked so i had to toss it. i did have a scout 3 duffel at one point and found it too fussy. and at one point i think i looked over a backcounty 40L duffel and found the same. i guess the softbag 3 is the next piece of gear? or anything to consider that i might be missing? i guess backpack option would/could be nice? THANKS for any advice. bike is an old BMW GS.
