After a full season on the Howler I can confidently say this is my favourite snowboard I've owned so far in 20+ years of riding.
I just got back from my BASI level 3 technical riding exams and couldn't have asked for a better board for that week where we had to demonstrate proficiency in steeps, berms, bumps, variables, carving, switch riding in all the former, and park (with probably the least emphasis on park - only goes as far as 5050's, boardslides, grabs, 180s & 360's on medium features). Before the exams was riding it a lot in the Montenegrin powder and trees, and I'm always hunting for side hits.
I didn't feel any need or desire to switch board for any of those tasks, and for me and my riding style it's the perfect do-it-all board. I'll still keep a dedicated park board for all-out park days, and a split for obvious reasons, but it really does fill the perfect all-rounder spot for the way I like to ride.
Not to sound like too much of a fanboy, but I'm going to buy two 157w Howlers next season incase they ever deviate from this formula. The only way I could imagine a better board for me is if they offered a premium construction, light weight offering, as it does feel to be on the heavier side compared to some of my previous boards. But who knows if / how that might shift the feel.
