I have decided on the CWB sol with Mobe bindings, now i just need to know, 139 or 134...I am 5'10'' and 155lbs, plus my sister is 5'1'' and 92lbs. Which would work best for us, more for me .
The 134 is probably best for your current weight. It will be too big for your sister but she might be able to grow into it over the next few seasons. If your still young, you will probably put on another 15 lbs, and be into a 137-139, so it could work out for the both of you. DK
NO. Go with the 139. It sounds like you're still growing and your sister is too most likely..? Besides, it's easier to learn on a bigger board rather than vice versa.
