Shah269,
What size canopy are you jumping? A 9 Cell doesn't say much but if you want soft landings you should be jumping a 230 sq ft canopy of just about any manufacturer.
I have been jumping for 37 years and being about the same weight as you, I too had hard landings on several of the canopies I tried over the years. Back in the 80's, the squares I jumped included the para cloud's and the cruise air/lite's. These were F111 fabrics and I could shut them down to a tip toe landing every time.
With the introduction of the zero P's, I noticed a lot of differences including the forward speeds when landing which forced me to run. Having a bad ankle which doesn't allow me to run, I proceeded to test a lot of different parachutes out there. I concluded there are only a very few models that you can shut down even in no wind. The Silhouette which is made by PD is one of those canopies, however the timing when flaring is critical. The best one out there is the PD Spectre. It's a 7 cell and has great performance with nice flare that isn't as critical as the Silhouette. You can go to their web site and request a demo which they let you use for 2 weekends, even longer if you need it.
I actually have both canopies and if the winds are 10 or better, I fly the silhouette and for very light or no wind, I use the Spectre.
Stay with it and try a few canopies, but make sure they are 210, 220 or 230, they will let you down easy.
Good Luck You live more in the few minutes of skydiving than many people live in their lifetime
