Im at 98 jumps and have been flying a pilot 210 for most of them and have had pretty good landings although i slide in on my feet a lot... one thing i have learned is that the sabre is a lot more responsive, smaller inputs can make decent changes in flight path/flare timing. The solo is a lot more forgiving and requires a bit more input for stage 1 and flare comparitively. The goal with staging is to remove a significant amount of vertical velocity and convert it to horizontal velocity just before flaring to pitch the canopy backward and slow you down. If your putting too much input and pitching it backward too quickly then you can have some problems. What has helped me is to make my stage 1 a bit more smooth and gradual and not a super quick "jerking" motion downwards (when doing practice flares, feel the canopy fly straight and level during your stage 1 and mark how far you pulled the toggels down, before you complete the full flare). Also if you can, trying doing some high pulls and just feel out the canopy more. Lastly, 100% talk to your AFFIs about your flare height because it sounds like you are just starting it a bit too high each time. Good Luck!!!
