I think the only arguable advantage of the 3-d pattern is better flex, but I would love to see some emperical evidence here.
 
This leads me to Burton's new concept...
 
if anything it makes the flex uneven compared to 4 hole.


hey guys, i parsed this down a bit and wanted to respond. my apologies if it does not all make sense as i have only had my first cup of coffee.

1st a bit of history. 3d was created waaay back when everyone was riding various 5-hole patterns. Burton had one. Nitro had one. And a few other companies had some crazy hole patterns. Check this image to see.

it didn't give you a lot of versatility, but this was back in the dark ages of snowboarding. note how there are only these bolted on edges near the back foot.

3d was created around the same time as 4x4 (or 4x2). each was toted as the next greatest thing. 3d gives you millions of stance Options. 4x gives you millions of stance Options as well (especially if you compare disc movement horiztonally or vertically). i am not sure regarding questions about stability or the triangle, but yes a triangle is always more stable than a square. it's basic geometry. you have the exact same base, but less material at the top to support which equals less total surface area (in 2-dimensions) and less total volume (in 3-dimensions), but i digress.

the two biggest advantages of 3d? flex and weight. these are both related directly to the # of inserts in your board. 4x4 or 4x2 requires you to place two sets of inserts up and down the entire length of your board. this gives you great stance adjustability but each additional set of metal inserts: 1. increases the weight of your board and 2. adds another "dead spot" in the flex. of course both these points are marginal but do add up if you decide to add a lot of insert packs.

3d minimalizes both of these by reducing the number of inserts required and tightening the range of inserts. this: 1. decreases the overall weight of the board and 2. decreases the number of dead spots.

here's a super techie diagram from a fruitbooter site. Big%20smile

burton's 3d does not make flex uneven because the stance pattern is focused around the center of the board (toe/heel not tip/tail) at any given point compared to the edges.

side by side comparison.
honestly, i think the 3d works great for most burton boards. this means that the board is set back from 0.25mm to 0.5mm. where things get tricky is that 3d was never designed for centered stance boards. i have a really tough time on 3d getting the exact stance i want on a twin tip, centered stance board and want to keep a centered stance. 4x pwnz burton in this aspect. at the end of the day, tech has come so far that either 3d or 4x2 works great for most snowboarders. most snowboarders will never know the difference or feel marginalized by either system.

2x takes burton's 3d and all of

For the record it was actually Lib Tech that invented the 3d hole pattern. They realized the 4x pattern was more functional and universal and switched to it. Burton scooped up the 3d pattern and patented it.

Don't generalize all the slider's into one category as they are not the same. Capita's Freedom grove easily beats out Forum's I-Lock system in functionality and flex.

i'm hoping if EST can hold up to the durability tests than i won't have to make any sacrifices.

and i do like the EST, but i hope you can see that i think it's probably 50% novelty and 50% truth.

ok after spending a season on the ICS/EST, I am not sure I can go back.  To those who say there is no need to easily change your stance, I used to agree.  But now that it is so easy I will change from a slightly set-back for a little bit of morning powder, to a centered stance at the park.  The flex is quite the improvement, although if you ride it without the EST bindings I didn't notice much of a difference.  I have ridden the X8, UnInc, and now the 09 custom ics and even though at times I think Burton is over-hyped these board/bindings setups are awesome.

durability of the ICS - great, durability of the rest of the board.......

seems this topic had been dead for awhile, needed some reviving.

Great post, especially with the late release Burton boards.

I'm looking hard at a CUSTOM ICS.  Busted my tib/fib and my leg isn't "quite" straight so being able to get the angles - just so - is very interesting!Wink

If you get the EST bindings it is truly a great ride.  I am still questioning on the durability...also the hardware is pretty expensive. It will cost you approx $25US for a set.

I'll pay extra to ride pain free...

It's cool that I now have a better option.

Jenn just told me no 162W's in the custom ICS here... I was really hopeing to buy here since they are nice enough to provide this great resource! Big%20smile
