I presently shoot a #50 Rebel using Carbon Express Heritage 150's w/100 gr inserts and 125 grain tips. I recently purchased a Mamba @ #45. (both weights @ 28")

Would those arrows shoot well in the Mamba? I've shot a few and they seem OK, just haven't stripped one to bare shaft. Also, what would be a recommended arrow for the Mamba? I understand tuning arrows, just don't know where to start with spine. Thanks in advance.
