I know it's not due for some time, but I picked up some AW IMR 18350s for my upcoming BAM, and I also grabbed the 2 bay XTAR Charger. It's going to handle the 18350s, and I'll keep the Pila for my 18650s. The XTAR has spacers that can be combined, and that makes it a nice set up for the 18350s. It takes two spacers per side for 18350s to fit, so if you're thinking about getting the XTAR,remember to get an extra set of spacers. You can thread multiple spacers into each other, which is handy.
I topped off the 18350s and they all came out just a smidge over 4.20 volts--4.21 to 4.23. That's close enough that I'm not worried about doing any real harm to the Batts. I don't have a device that takes 18350s for now, so I can't see how long they'll hold at voltages above 4.20 with use. Some say they'll drop to 4.20 after a few hours off the charger, but mine are holding steady right now.
In all the XTAR is a nice little charger for the money. It comes with the auto cigarette lighter power attachment included, which can be handy for road trips. It can also be powered via USB, which is also nice, but you'll need a USB port that can handle load or you can fry the USB port.
If you don't want to spring for the Pila, or need a back up for your Pila, the XTAR is a nice option.
