I have been debating for the last week about upgrading my old tk40. I know i want to stick with AA batteries since i am well stocked on the eneloops. Right now i am torn between getting the fenix tk41 or the sunwayman M40A with the xm-l led. Now i know most of you will say to get both and believe me if i could, i would but i must choose. I guess the info i seek is, is the m40a rated at 600 otf lumens? Also i see it it does about 32,xxx for lux compared to the 18,xxx that the tk40 does. Will there be a noticable difference in throw? I am looking for something similar in beam pattern to the tk40 but brighter. I orginally was excited for the zebralight q50 but after thinking it through i want something with a little bit of flood and some throw. Right now i am leaning towards the m40a since it's more compact and the design of the light is simply beautiful. But would i be wowed enough that it outperforms my tk40? Any input or even pictures are appreciated. I searched and the m40a with xm-l led beamshots at distance seem to be few and far in between.
