I actually have never used the ones I recommended but they are on my "to get" list. I have used many makes and models and all of the Hibben models. Most of the Hibben models are too small. Trust me, you will want larger knives for throwing. That's why these new Hibbens look great. Also, the steel they use in the Hibben throwers is actually great for the application. 420 J2... not great for a cutter but for a thrower it rocks. It's soft enough that it's easy to sharpen the point back up when it gets blunted and also the knives are very tough and if they take a hard impact they will slightly bend instead of cracking in half. The price for the 3 knife set is also good.
I have used knives with the swells in them like these and I have never had a problem with them protruding and interferring with my grip or release. Like I said, can't really say on these as I haven't used them yet.
Peace-
