Hi I am new to the site. I installed a century insert a couple years back and now on the Hunt for a larger insert with better burn times. The blaze king princess seems to have everything I want although a little pricey. I read the threads comparing secondary tubes to a cat and am set on getting a cat this time around. Does anyone have any experience with the high valley 2500 insert? I can't find many reviews online. I really like the BK but trying not to break the bank.
