Tuning has left me puzzled... help needed

[General Dogs]

The facts of the case:
1. I shoot left handed (recurve)
2. I normally shoot Easton Plat Plus XX75's
3. I have been trying out some ACEs in readiness for outdoor next year
4. The ACE's are roughly the same spine rating as my Ali's
5. The ACE's are fractionally shorter than the Ali's (about 5mm)

I will be deliberately vague regarding spine rating, draw length and draw weight. This is because I would like to get a view on the results of my bare shaft test rather than any preconceived ideas based on spine charts.

With my Ali's, the bare shaft sits nicely with the group and I can sight on and hit the gold with reasonable confidence. The only downside is that my sight ring for this arrangement is bang in line with my string.

With the ACE's the bare shaft sits nicely with the group, but the group lands at the black/blue border at 9 O'clock.

Given that my sight ring is already on the string line, I am reluctant to move it further left to compensate for the arrow position as it will move inside the string/riser aperture.

Are the ACEs spined correctly for my setup?
What are my options?

They sound weak to me. Try the next spine up or decrease pile weight

My first thought

How have you set up your centreshot, have you made any adjustment to your button tension from you aluminium setting, compensated for the different diameter shafts(sorry had to ask) and what distance were you shooting?

Many years ago I changed over from X7's to ACE's, the dealer told me what I needed.
Having set them up I went to the Silver Dollar shoot and shot one of my best rounds ever. (NDY is still chasing it).
When I visited Wales Archery They asked 'how the arrows were, having heard I'd shot well'. I told them they were great, but that they gave a slight flicker while in flight, they changed them for me and gave me the next set down which made them slightly whippier. They went perfect after that, pity I didn't follow.
But what I'm saying is, if you know of any way of trying a different spine then it may be worth looking at....

Centre shot was set up with the help of a coach.
Button pressure slightly weaker to get bare shaft inside group but pressure setting not much different to that with the Ali's
Arrow rest and centreshot amended to suit ACE's
Shooting 20 yds

If the bare shaft is landing with the group then the spine is right, don't mess with it ,set you sight to bring the arrows into the center and do a walk back to set the center shot.

There lies the problem though....

My sight ring is already in line with the string. If I adjust it left to move the arrows into the gold, the ring will fall well inside the space between the riser and string - I always thought the sight ring should be just outside the line of the string. Should I just move the sight ring and get on with it?

General Dogs, a normal set up(if there is such a thing) will have the arrow point just right of the centre line/string line of your bow for a left hander, yes?
The sight, normally, would be more or less directly above the arrow, yes?
The string line, when at full draw, would be just to one side (left) of the sight ring.
What you describe has the sight setting, closer to the sight window than the "normal".That usually means soft arrows, as BE says.
I mean no disrespect to your coach, but is it possible he set up centre shot, forgetting that you shoot left handed? It can happen. I've had arrows brought to me with marks on the upper fletching. Coach was puzzled, as it's usually the lower one gets marked from contact with the rest. The archer was left handed;the upper fletch was in fact the lower one!! It's worth a visual check, and costs nothing.

First point - forget the aluminium arrows, they are not relevant
Leave sight position and centre shot as they are as probably fine as per coach set up.
Before you try to start tuning move the fletched arrows to the target centre. Button spring or draw weight adjustment. (With the same Easton spine the ACEs are going to be a stiffer than the aluminiums).
Finally with carbon arrows you need to bare shaft tune at a longer distance than with aluminium arrows. Start at 20 metres OK but move out to 30 metres for a reasonable result.

I had a very simular problem when I changed over to ACE's because the straighten up quicker they fly closer to the bow, The problem is your sight!!!!
I also had a Arten Europa if you look at the rack of your sight you will see that it is set over towards your sight window by about 12mm, this I found left no adjustment on my windage and the pin was fully wound in. Try spacing the sight away from the riser to give yourself some adjustment a 10mm plastic block works a treat.
I know this is looking at the problem from a different angle but who knows I may have a point, I have found no other maker of sights that offsets there rack in such a way.
Also which side of the string are you sighting down when you shoot, inside (riser side) or outside.
