I love my MH20. The problem is, the 1-inch head is just a tad too big for dress pants. The Klarus XT1A is lighter and thinner (about 0.75" dia. throughout it's length) but still throws a whopping 1,000 Lumens on high (compared to the MH20's 900 lm on turbo). The XT1A can also take in AA batteries in a pinch (at the expense of lower light output).
This will add to my collection of other torches:
Nitecore P12
Nitecore EA2
Streamlight PT2AA
Streamlight Jr Luxeon
Mini Maglite (Converted to TerraLUX LED)
Maglite 3D
