16" barrel can utilize both carbine gas and mid length gas system
The closer the gas port is to the chamber, the higher the force that is
applied to the bolt.
By lengthening the gas system with mid length, the bolt and receiver
lifespan is somewhat increased and the felt recoil is slightly dampened.
That is the merit of mid length over carbine gas system.

第一双ski boots 2010年初买的 Technica Mega 10 Ultrafit size 9.5 width 104mm

买回来挺好，不过觉得滑雪到学习carving时进步很慢。10-11雪季中去ski resort旁的

然后回去第一次试鞋的地方量了，还是9.5。我坚持要了个8.5号的technica dragon

之后试图垫3双鞋垫，不过不能解决问题，遂决定买新鞋。

发帖数: 164 | 29 看了这篇文章，
http://www.real-world-physics-problems.com/physics-of-skiing.ht
其中讲到：
“A purely carved turn can be done with a ski that is flat on the snow or
tilted at an angle to the snow.”
如果ski是平的，purely carved turn半径(R_T)等于雪橇side cut radius(R_SC).
如果有立刃，角度为phi，purely carved turn半径(R_T)变小，
R_T = R_SC*cos(phi)
当然,实际上ski是平的确实作不出carving来，所以这样说好一点，立刃角度趋近于0的
时候，purely carved turn半径(R_T)等于雪橇side cut radius(R_SC). |

如果只考虑你说的这两块板，其实本质技术没啥差别。我能看到的就是sidewall有点差
别。head传统一点，salomon用hybrid sandwich脚下刃效果好一点，但容易wear out。
不过我们一般也体会不出差别，而且也用不到wearout的级别。
head说他家转弯edge contact好，其实也就是那样，就是最近的新潮流加了tip的
rocker。
但根据你的身材看，rev85 184太长了啊，radius turn 17多。你重量倒是可以驾驭，
但拐起弯来肯定比xdrive要困难些。相比较那个rev80 177的板子更靠谱一点。
板腰嘛，看你是西部还是东部。西部就宽点，东部就窄点。窄的好拐弯，宽的适合进软
雪。
你这个级别，要考虑的基本就1点: 容易不容易拐弯。喜欢大回转呢，就找个稍微难拐
一点，radius大一点的。喜欢小回转呢，就找个容易的。
板子越长越难拐，板腰越粗越难拐，板子core的材料越硬越难拐。找传统camber板或者
20rocker80camber，rocker别再多，再多刻不住雪了。 |

it's great for frequent and short radius turns
But for bigger-radius and faster-speed turns, leaning the upper body
provides better power transfer and stability. It really helps to hold the

总体来讲你上身还比较稳定，不错。但你angle 不够，重心不够低，太高。但你如果硬
增加 angle,肯定就摔了，因为你速度不够。但你速度太快就一定能angle吗？也不一定
，如果你的ski太短太软属于 beginner ski, 速度快，它可能咬不住，或者太短容易转
而速度起不来。或许你需要一个下一个 level的skis. 你需要 ride ski, respect its
radius. 你小于 radius 就Z turn和很多 skidding.
还有你的重心有点靠后， 我喜欢说让ski在你身下，而不喜欢说重心靠前，前者容易强
调用腿的伸展来做到，后者容易让人身体来调节，这是初学者的做法。
我个人突破是通过用了 advanced ski来实现的。用了两个 season,突然 get it. 刚开
始我老是转的小于半径，否则我老觉得太快，超出自己的 comfort zone。突然一天，
