I really like my 561 (same as your 560 except tan) but it's a little hard to open. The assisted opening models are very handy.
I wore the 301 on a five mile walk very late last night. Also carried my Leatherman Serac3, Glock 19 with TLR , Safariland ALS lightbearing holster, spare mag, keys, etc.
Didn't notice the weight of the 301 at all.
