Although the fEARless cabs are very nice, they are too heavy and big for a comfortable one hand carry IMO, so if I were in your situation, I would get instead either a Barefaced Big Baby II, or an Audiokinesis Thunderchild 115, depending on your volume needs...
The Big Baby, at 29lbs is easily a one hand carry that can hang with a drummer at loudish volumes, and with very flat freq. response, almost comparable to the fEARless cabs, while being much lighter than it's F112 counterpart. It is probably as loud as some 80's and 90's 4x10's, although maybe not as loud as some of the more modern, higher end 4x10 cabs out there. As someone already mentioned, it has an adjustable crossover freq. so you can gradually disable the horn when you want to use some distortion and use the woofer's high frequencies instead.
If you need the extra loudness, and perhaps an even flatter response, then I would go for the Audiokinesis Thunderchild 115, which uses a custom Eminence Kappalite 3015LF variant, so it would be even louder than any 1x12" (certainly closer to the higher end 410's spl requirement), but still light enough for a one hand carry at 37 lbs, more compact and way lighter than the fEARless F115.
It also has a very flat freq. response (there are even some Thunderchildren being used as studio monitors), and it has the advantage of having switches to roll off the treble (which would be nice for distortions), to smooth out the mids or make them grindy, and to switch between 4 ohms or 8 ohms, and it has 3 pluggable ports to roll off the low end a bit, or turn it into a sealed cab, so it is definitely one of the most versatile cabinets out there.
Either one of these would be an excellent quality product, and with great customer service, so no worries there.
