Hypothetically, would the IS still be able to burn with secondary burn if the cat were removed or plugged and run in bypass mode? 
Not being able to see this stove in person, I'm not sure what the inside looks like. Could someone with an IS post a pic or a link of the upper inside of the firebox. I've looked all over and can't find anything. I've seen the drawing on the WS page, but that doesn't show from the front. Sorry, I research everything to death before committing. Thanks for being patient!

		 To get all that for a reasonable price makes it so much the better. I'm awaiting with interest the beta reports on the new 211, basically a smaller IS. I have a feeling that puppy is going to be my next main stove, with the Keystone assuming the back-up role.
 To get all that for a reasonable price makes it so much the better. I'm awaiting with interest the beta reports on the new 211, basically a smaller IS. I have a feeling that puppy is going to be my next main stove, with the Keystone assuming the back-up role. Woodstock has some of the lowest prices on all replacement parts, of any maker. As far as efficiency, I think the BKs and Woody hybrids are all rated around 80%. There are other hybrids hitting the market as well, and other cat-only stoves as well. I wish I had a Regency dealer nearby to check those hybrids out. But let's face it, the vast majority of buyers want nothing to do with any type of cat, and want the perceived simplicity of only one lever. That's why there aren't a whole lot of these nerd cat-type stoves out there.
