I EDC G10/VG10 Caly3.5 for more than a year. And for my use there is no better Spyderco in current production. As much as I like Para2, I would take Caly3.5 over it any time. I love Caly3.5. IMHO it is better slicer, looks better, more compact in the pocket. I prefer low riding wire clip and back-lock. Please, understand me correctly. If Spyderco wouldn't make Caly3.5, most likely I would carry Para2, but fortunately for me I have Caly3.5.
If 3" blade can be sufficient, I will recommend Native5. I started to carry it few weeks ago and very impressed with ergos and cutting abilities. I sharpened it once and S35N takes very nice edge.
First choice: Native5
Runner's up: Caly3.5 G10/VG10, original C83 Persian, Memory
