The pockets on blue jeans are ideal for carrying the Native and the Delica together. You can then reverse the clip on the Endura and carry it in your other pocket for use by your non-dominant hand. For variety, the BM 710HS takes up little more space than the Native and your Delica and Endura will make it behave. I have to say, though, that every time I've replaced my Native with my 710 (to get used to the feel for my pending 710HS), I was overcome by a wave of guilt and quickly put the Native back.
