in my experience b50 tends to vibrate way more than anything else. i love dynaflight 97 great stuff
That 18 strand B-50 is probably your greatest source of vibrations. A 14 strand string is more than enough for that weight. Try a FF string like BOWMAN suggested. I use a mix of the two myself, but that's another story.
Like I stated above, it's all about trade-offs. For myself, using a shorter draw, and shooting heavy hunting arrows in lighter weight bows, I would keep those tips just the way they are. That would give me optimum performance for my requirements. Everyone's requirements differ to a certain degree, and to find what best suits your needs you have to experiment.
So, it's safe to say, most of advice we give is derived from our own experiences. But the best advice I can give, is not to depend so much on others advice, but learn this stuff first hand
. From the looks of your work, you already have a very good understanding of your own requirements................ Art
