I would not personally recommend a Treeshark at that weight and especially draw length. As others suggested, a Tigershark, Interceptor or Safari glue on coupled with the appropriate adapter would be a better choice IMO.
If adapters are not your thing Simmons offers the Interceptor as a 190 screw in and the Safari as a 205 grain screw in, either should work for you.
This year I set up a new bow that is lighter than I am used to, it is 47# at 28" and I chose Tigersharks for that rig.
