The track choice really comes down to the snow conditions, riding style and personal preference. Set up snow, and or late season, less snow, trails, prairie, ditches and hill climbing leans towards the competition track. It has a stiff lug that doesn't really flex and is a digging machine until you hit something to grab and then hang on!
Deep and steep, more snow, early to mid season, and more flotation for mountain riding leans towards the powder track.
I think both tracks are versatile and very capable of doing all kinds of riding but it really seems like most guys like the powder track for the do all.
By the way, good choice.
