Both are great bags. But the 511 is definitely the way to go. Stellar price you paid for it. You can’t carry a bag like that to my job. It has to be a clear see thru bag. PS I put bright para cord loops on everything too. The old eyes don’t see as well as they use too.
I have both. Honestly, for daily or hiking use, pygmy falcon II is the way to go. For bug out, rush 12 might be more solid and durable for serving the purpose.
