Oh god, the places you've been renting from have been sizing you based on your height instead of your weight. A 160+ is actually too big for you at a beginner level.
Based on your weight and ability, something in a 155-159 would be ideal. So that 159 should work, but if they offer the model in a 156-157 it might be just a touch easier to learn on...
yeah i have always said that, but ofcourse, "they know best".. ive always loved boarding.."hated" the board.. thanks for the advice..actually have a lesson booked at chill factore to ensure im not too rusty, will ensure they slap me on a 159 just to be certain
