This is something I've battled on a handful of Hoyts, and I'm now battling it again on two of them. I want to say we had an earlier thread here discussing the same thing but I can't find it.
This time around it is with a 2018 RX1 Ultra and a 2020 RX4 Alpha. In both cases I start with nock level, cams timed dead even and then start tuning bare shafts. On both bows I now have the bottom cam advanced ~1/8" and the arrow either nock level or nock low at brace and I'll still get a nock high bare shaft. Seems strange to me that the with the RX4 (as an example) I now have the arrow visibly pointing up at brace, the bottom cam ahead, and I still might be a little tail high / low impact.
I run a 300 spine arrow, 27.5" carbon-to-carbon, 175-200 grains total weight up front, 71-74# DW, 29" DL. I don't think this is a spine issue but maybe some testing is in order. Not fletching contact as we're talking bare shafts. I don't think it's nock pinch, just re-tied nock set wider and put a new loop on one bow.
So - what ideas do you have?
Rest is a Hamskea, I could play with launcher spring tension. I could play with launcher blade timing - I have it coming up to full height maybe 6" before full draw.
Has anyone seen differences based on where the arrow is with relation to the berger hole? Generally, I start middle of the arrow through middle of the hole.
I feel like I shouldn't be having this much trouble. My Hoyts used to be easy peasy, but feel like I haven't been there since my Carbon Defiant Turbo.
@ontarget7 - You still hanging out here? I know you had good luck tuning the RX4...
