Thank you Tom for your input. Not sure why I started to fly the 180 turn instead of two 90's with a proper base. It seems like I could shallow the bank to make a longer turn while adding spoiler and still judging that looks about right if needed, or I could steepen the turn to shorten if needed. Just seemed simpler . I do see other posters advocating the 180 "button hook". I think I will go back to the squared off pattern.

The "button hook" was relating to a turn close to the ground if you go past the runway center line (low bank angle, late turn, not allowing for x-wind, etc.), not the "180 from downwind to final".

As to me (and what I taught) was to fly a downwind that gave a ground track parallel to the runway, turn ~90* (base leg) when touchdown is ~45* behind you, turn final when needed to line up but NOT overshoot the runway.
You could adjust dive brakes/spoilers as needed (usually start with ~1/2) or angle the base in or out as needed.
Once on final, you should only need to "fine tune" to hit your mark.

Listen to the wind noise, scan against the horizon (pitch attitude), glance at vario, keep asking, "Does it look good, does it sound right, does it feel right?" Adjust things so it's all good.
