if I feel like dying some back country stuff. Thanks
Okay, you need to edit your post....this is some bad juju if go BC.
Here's my thoughts on your situation. With size 11 boots, I'd be a little concerned about the width of the 154 Jamie Lynn at 247mm...that could be pretty narrow for your boots. The 154 TRS with a 253 waist might be the safer choice.
Also, if you think 157 is the right size for you, have you considered the TRice? Its a better all mountain board than the TRS and the waist would be even better for your boot size.
As for the length, not considering the waist, I think at 160 lbs, you could go with a 154 or a 157 and be fine either way.
