Welcome to CPF Cary, why dontcha stay awhile!
The Arc is and always will be a classic. I still carry mine every day, everywhere. That said, if my wife hadn't borrowed my L0P (permanently, to replace her Arc), I'd probably be carrying it.
The only issue, as digdug and greg point out, is the runtime. If you use it all the time, and not just for short bursts, you might want the Arc for the time between feedings. Still, I use rechargeables in both the lights, so it's not a big deal.
cheers, and welcome again,
