I'm not a huge fan of Sam Smith's IRS, Stone's is much more complex and bold. Don't get me wrong, I really like Arrogant *******, but it seems to have become a "trendy" beer to drink within the FM walls. I've had their Oaked AB a couple times, and I prefer it over regular AB, by a narrow margin, but not enough to justify the huge price increase. Personally I've been on a rye beer kick as of late, Bear Republic's Hop Rod Rye is one of the best beers I've ever had, I highly recommend it.
