I have had my Silhouette now for just over a year.  It's a great first canopy for anyone!!!  I did my research and for my first canopy I decided to get a Silhouette 190, I weigh 155 and have an exit weight of about 170.  I am at a 1:1 ratio, and this canopy performs!!!  Great toggle input, fast turn recovery, and a great glide.  Yes it's a little heavy on the front risers, but I doubt you are buying this to do any type of swooping.  I would recommend this canopy to anyone that's looking to stay a little conservative yet really fun to fly, especially students in transtiton!! I love it!!
