Just recently Life Like Canada has released a set of limited edition GP9 "Chop Noses" for both Canadian Pacific (GP9u) and Canadian National (GP9RM). They're part of their proto 2000 series. They look great, I've even seen a few of these up close. However, I've heard that Life Like are notoriously DCC unfriendly. If I were to install a decoder into one of these limited edition locomotives, what would be required, and which decoder should I use to allow for the best fit? Suggestions?
