wyoranch: In my opinion, you have come up with the ideal solution - increase the LSA weight to include simple single engine like the 172 and Cherokees. If the intent is to increase the pilot population, this would open up the field of available aircraft. Maybe even with the stipulation that it is daylight only to eliminate any dependence on instruments. It's also my opinion that the C150/152 class aircraft are easier to fly, i.e. safer, than most LSAs I've been around.
