Have you ever run a 200? I don't mean to be a smart :censored: , but the 200(T) is a machine. I'm continually amazed at that saw's power and what it can do when asked to. The 192 is a fine saw, but I'd not trade it's weight for it's power. Have you had problems one-handing (for comparison purposes only, of course...) a 200T? It's a superb saw in every way.
Myself, I'd compare the 192T/200T to a 390/440 or even 460 ratio. The 390 is a fine saw in it's intended role...until you run a 440 or 460.
(The 192 has a horizontally split polymer case, right? I thought I remembered seeing that on the ones I've handled.)
All of that said, you've got a fine saw in the 192T. Use it and use it well. When it came time for me to buy a climbing saw, I was very close to buying the 192, but well...we see how that turned out...
