thankyou for your help

i have bought the 159 as it was significantly cheaper than the 161, i
figure this should be ok as my height is about 181 cm, although i do
weigh about 14 stone....

at my level (beyond beginner but havent ridden for 3 1/2 years) i
reckon its a good length, and the money i have saved will go most of
the way to buying me a better set of bindings

bring on the snow!!
