im far from an expert but i learned alot while designing mine, its basically based on my NS frame with higher seat tube, shorter stays and a steeper head angle, from what i can gather a good trail is around 65mm, i believe the butter bean is around 70 and my NS was 62, my new frame is 65.8 using the dmr trailblade forks, they have an rake of 40mm. new frame turns nicely and you can get the bars to 90° until it wants to flip. Short rear stays are good but unweights the front wheel and decreases what Ryan explained as "rider confidence" thats why its good on these new breeds of frames people are getting to put a slightly longer stem on to get your weight more equal over both wheels while keeping the bike short for tighter turns
