Lh-oab: oh, I get that a lot at my school. For trial lessons, we ridgely hold to a weight limit but this can mean certain instructors loose out. With students, however, it appears far less enforced, and when taking into account the Market right now, it's hard to see an instructor turn away students because they can't be paired up because the 150 is in play! Either certain instructors loose out or, due to pressure, go with it. I'd just rather see it out of favour. Choice is c172/pa28 et al. 150 for cheap self-hire. Just a thought!
