if you want throw, i'd get a Spark ST6 that takes 2x123 batteries (since you mentioned in another thread you already carry 123s). price is competitive with Apex Pro, has a brighter hi and a dimmer lo, is a little bit lighter, and has better battery life. if you want flood, you can make or buy a bottle cap type diffuser for the Spark.
one thing about the Apex Pro that hasn't been mentioned is this (i know this is a kind of a carry over from
another thread, but bear with me): the hi spot is 200 lumens at 1 hour, the lo spot is about 110 lumens at 7 hours, the hi flood is about 50 lumens for 5 hours, and the lo flood is about 15 lumens for 12 hours. the runtimes for the spot beam at the levels listed are fine, but the lack of a lower lo (something around 50 lumens) is a real bummer. the runtimes for the flood beam, however, suck.
i think when you're backpacking, you really should have a light that can give you 40-50 lumens for 10 hours or more and has a mode of 10 lumens or less for 20 hours or more, and the Apex Pro really falls short of that. even more than the bulk or the bad hinge, the poor choice of light levels and low runtimes were what really turned me off of the Apex.
now i use a Eos. the Eos barely meets my runtime criteria and i've been happy with it. but it sounds like you're looking for a brighter lamp than a 70 lumen Eos. check out the Sparks.
