snacker<<snip>>I still feel I need more practice with landings on a trainer, although I have other planes to fly.<<snip>>
What else do you have to fly? Anything that lands easy?
Don't get me wrong, a Senior is a nice nostalgic plane, but you're already landing and accustomed to ailerons.
If you're in the mood for a nostalgic plane, go for it. Otherwise, you can get a 4 channel trainer for the same money or less. Or, if you already have a nice landing plane, that would serve the purpose.
Good luck,
