I built a 9A and converted it to a 9. At the end of a landing run with the stick on the back stop at approx 15 kts the nosewheel hit a series of bumps that resulted in the spat getting damaged. After that I was very nervious about landing on grass.
Other things you might want to think about.
- The 9 is cheaper than the 9A so you can spend the difference on TW training
- The 9 looks so much better than a 9A
- The 9 is about 25lbs lighter
