The question is why do we do touch and goes? Only reason is to get a few more circuits in a given time period.. In real life flying you are either going to land or you are going around....even go-arounds in Mooney are a handful with strong pitch up... Combine the strong pitch up with a strong crosswind ( the norm in Northam) and possibly a bounced landing (very, very easy to do in a Mooney)... I rarely do them in mine ...better to practice go-arounds
HMMMMM
A touch and go is a go around where the wheels have touched the ground, or a go around is a touch and go where the wheels didn't touch the ground. Either way if you cannot control the pitch up when power is applied then you need to consider whether or not you should be flying that aircraft, or be taking steps to reduce the pitch up forces.
As for resetting the trim before applying power on the T & G, the less said the better about that. Wasting runway space while not accelerating, not a smart idea. If you're going to do that better to plan on a stop and back track.
