why do the pros use top-mount boards for speed?

hey i see a few pros using the rayne avenger and chopped comet voodoo doll, those kinda boards are pretty similar looking, just wondering why pros use them instead of the drop-through or double-drop boards.. are they more stable at higher speeds being top-mount?

speed wobs dont actually exist, so stability at high speeds is all up to the rider

More stability, but less traction. When you lean a lowered board over in a turn, it pushes sideways on the wheels compared to a high (top-mount) board which pushes down on the wheels.
Top-mounts grip more, which is why people use them.

And there's the answer.
hahah

exactly what merrick said but i dont know what the topmount OS is

Well. Basically..

Top mount has more grip/ traction with less stability
Drop trough has slightly more stability with less traction
Double dropped has mega stability with lots less traction..

It all depends what you like.

Personally I rode a topmount OS this year because I like the traction side of things.. And you will get use to the stability differences

(By the way.. I could be 100% wrong)
dont meann to jump in on bugs's statement, but wouldnt that same principal apply to truck angles?
imagine this:

see how the higher truck angle the hangar is at a higher angle (kind of obvious i guess)
now look at this picture:

now for the purpose of this, lets assume that is a fairly low angle reverse kingpin truck (yes i know its an orgiinal truck im using an example)
pretend your board is like that in a corner, that angle , when you apply weight, the boards tendency will be to slide because that is the direction your weight will be pushing. if you have a high angle truck, the board wont lean that much, so you won't be applying as much horizontal force and you will simply feel centrifical force trying to throw you off, and creating more momentum in the direction you are aiming, i.e. you won't have to slide, you will be able to coast through the corner.
now think of that when you are going around a corner, if you turn hard on the second one, your board will get angled

Lowered boards have a lower centre of gravity meaning more stability and should also have more traction.

i must be a pro! hahaha.
drop wedge 4 life.
only downside is that its slightly harder to foot break them, but just like the very slight loss in stability you get used to it and dont notice it before you know it
merrick just out of curiousity, what kind of baseplate angles and hangar widths were people using OS, and did anyone run cast trucks?
james kelly rides randal 180s and i'm pretty sure he runs 50* trucks too.
45* plates seem to be the most common, but its all personal preference.
nah man, no one runs cast trucks. only james kelly.

and louis pilloni bro... he still runs the good old paris trucks

YOU WHAT!!! bro lowered boards will slide and lock as much as the next, man up at the next hairpin and let her rip!!!

It's the speedcheck craze..... Eveyone wants to break into slides instead of using their feet to break. Sliding the board gives you that advantage of still having both feet locked in and able to hold your tuck coming out of the slide, instead of readjusting from a foot break.

Top mounting flat decks such as the Rayne boards gives the guys the advantage of sliding them. A lowered speedboard has a much lower centre of gravity and just doesn't have the same responsivness to break into a slide. It wants to stick to the ground and is more of a board for straight out runs with high speed. They can be pre drifted but it's work.

hope it helps
james is on 42 degrees and red elims
