I went with 350s for my new longbow based on the weight I am looking to achieve and while comparing 250s that I have when shot from my Schulz longbow.
I am shooting 250s cut to 30", with 145 grain points, standard inserts and based on what I can see they shoot fine. Paper and bareshaft tuning these out of both my Schulz and my Mamba recurve (about 62# at my draw length) showed accurate spine. If going to a full length arrow, with what will be around 75 pounds in my new longbow, 100 grain insert and 160 grain Stos heads with adapter. I anticipate I should be really close and was anticipating that I might have to trim the length some to stiffen the spine. Shawn, you think I am still too stiff? Honestly I am somewhat guessing so I may have spen $100 for nothing. Thoughts?
