Erns, great review! That Nitecore is one great looking light! One of my buddies ordered one so I'll have to go check it out in person. For some reason I thought it had a more TITAN/U2-like interface so I'm a little disappointed to see that it uses the twist on-off method to switch modes. The HDS Twisty will have a 2AA battery pack when it is released in the near future. IMHO an excellent substitute for the L1, and American-made if country of origin is important.
