For a jib deck the 151 will be awesome. With the 154 there is a 2 cm difference in contact length, a fraction of width, but at your weight the 151 will be great. If you want to sneak a little more well rounded performance out of it then you could notch up to the 154 (but in that case we would likely suggest another model).
Sounds good man. Definitely appreciate the advice. Tell your boss you need a raise
