Hey Joey, we're practically neighbors (I live in Japan). I have the LSH-S, LSHFP and the Arc 4+. The Arc 4 is by far the most flexible- you will not regret getting one. Although the LSHFP is much brighter than the LSH, the beam is much tighter so you don't get that useful "spill". When I first got my LSHFP I put the LSH-S in the car. After a few days I reversed them- I just found the LSH-S's beam more useful. But now that I have the 4+, well... (at least until the next great Arc).
PS: also pick up an AAA for your keychain. It is the Arc that I (and my wife ) use most often.
