Since I have shoulder problems I cannot pull more than a 50 pound draw weight. I currently am using a 45 draw weight. So my question is which bow would yield the fastest arrow speed when set at 50 pounds?
Trying to take IBO speeds and adjust down doesn' t always work since each bow has different characteristics. I could use the general rules of thumb (10fps/1" draw length, 2fps/1 pound draw weight) but they did not work out on my Firestorm Lite (off by about 15fps). So I would like not a calculated or estimated speed but real speed that someone has measured with a chronograph.

My requirements are:
draw length 28"
draw weight 50#
letoff 80% (can' t handle 65%)
arrow weight 334gr

My Firestorm Lite currently shoots a 334gr arrow at 219fps with 28.5" draw at 50#. I need to change my length to 28" so my FSlite will end up at 214fps. With it set at 45lbs this hunting season I am getting 209fps.

Also, I do not want to drop my arrow weight. This a whole other discussion I would rather not get into in this topic.

I would really like to be able to shoot 250fps+. I know there must be a bow out there that can do this.
