I have to say, with the wealth of information To be found here. It is very easy to get overwhelmed by The infinite number of choices. I understand the concept that you don't want to make a mistake with your next board purchase and get something you're not completely happy with, But I would have to agree it's pretty easy to over analyze the entire process.
Lots of people with diff. likes, dislikes, styles, riding conditions, terrain, etc. etc. etc. It will b next to impossible to get a consensus.
Having said that, your original question is Essentially a good one. I was considering posting something similar myself as I was thinking of looking for a new board To add to my quiver this season, And wasn't exactly certain which way to go.
I live in SE Michigan. Crappy hills, Lots of man-made, crappy conditions, lots of ice etc. I am 6 foot, weighed 195 lbs. when I started snowboarding. (.... About 250 lbs now totally geared out! :-( ). I learned to ride Those conditions with a full Camber, set back, all mountain, directional twin, 163 wide Arbor Roundhouse. It was Undoubtedly the wrong board for me At the time. I got some Questionable "expert" sales advice at REI, And purchased a long, wide, board That I didn't really need for my size 10 1/2 feet.
Since then I have acquired a Rome garage rocker 159, regular width, And a used NS proto-CT, 157 regular width. Both of which I love! (I even got to ride them in some shin & knee deep POW this last season! Both of them rode great!) On groomers they are fun, lightweight, playful, and easy to ride and turn. By comparison my 163W arbor now feels somewhat harder to turn and even a bit clumsy at times. Because of that, I was considering selling it this fall before the season started to put towards a newer different regular width board. And I love
that board!!! I rode it exclusively for more than a season and a half. (....Im 53 yo & 2.5 seasons in to my boarding btw!)
Now, because it IS a wide, I think I'll hold on to it to use as my POW board for the extra float. (...Whenever that opportunity might arise!) In Deep stuff, I don't imagine the width will make it all that much harder to turn!
If I decide to purchase another board At some point this season, I will go with something in a reg. width, either full or hybrid camber, maybe some grip tech or magna traction. I will most likely go middle of the road in length, probably 159-161cm. That, I think, should probably cover most of my bases for now.
This was my brief experience learning about getting used to, and riding new and completely different profiled boards. Take from it what u will. Ignore any or all of it you deem bullshit.
Whatever board u buy, Just ride the fuck out of it and have a blast!
Edit: (...I know, I know! Tldr!)
