I've been board shopping and I run into this weight range issue.
I'm 5'6" so a board that is 157 comes up to my nose and that's good for me
as a carver but I thought rail and halfpipe riders like a shorter snowboard.
I've been riding 155 boards for the last 2 years and as I go to stores now to buy a new
board I have a sales clerk ask me how much I weigh and they check the chart on the
snowboards and its got these weight ranges:
157 125-175
161 140-190
165 150-200
which raises questions.
Will I break a 157 board because I weigh 225 pounds when dressed for snow because I
weigh 50 pounds more than the board was designed to carry?
Will the board perform extremely bad because I weigh 50 pounds more than the board
was designed to carry?
Will my extra 50 pounds make the board flex wildly and cause loss of control?
Does Burton expect me to buy their 165 because its designed to carry an adult?
A 165 would be taller than me!
I'm not a big fat man.
I'm a little old guy and most of the kids on the hill are taller than me so I just
can't figure how Burton ranges their boards.
The board only feels your weight, not your height. The height between the nose and the eyebrow is a quick rule of them for day rentals when it doesn't matter, but for buying a board, follow the design specs.
Truthfully the "adult" boards are not designed for adults, they are designed for teenage-20 somethings because that is 90% of the snowboard market.
I'm 20, I am 5' 11" at 180 lbs. My freeride board is a 159cm and my park board is a 153.
My brother is more your weight, at around 220 lbs and he rides a 163 cm.
That kind of exemplifies how much of a range is possible, 6 cm range is perfectly fine for me between the two boards. A 151 would probably do me fine for the park and I've ridden my brothers board and I can ride that too.
I don't think you have to worry about "breaking" any of them, the boards are really durable. Me landing a jump wrong at 180 lbs is going to put many more times of force than even a 400 pound person on my board, and it survives me casing jumps all the time.
What you really want is to get an ideal weight for the flex of the board. Based on you saying that you like to carve fast and stay on the ground, bigger is better. The only time bigger isn't better is for spinning and jumping. On the ground, length gives you stabilty, edge hold, and speed. Stiffness reduces chatter so it is easier on your knees and you skid out less often.
Especially if you are in fact riding the Burton Air, which is a generally soft board, I would say the max size is the right one for you.
The really good news is that the largest sized boards are the ones least likely to sell during the season. Everyone picks up the small boards for park, and then there are just so many kids running around we clean out 151-157cm, but large boards like 159,161,163,165 are hard to sell. Both my 159 and my brothers 165 came out of my store at our tent sale. Mine was list $750 and I paid $200, his was list $650 and he paid $200, so large sizes are much better for deals and will fit you much better overall.
