I am wondering about all your experiences with weaker or heavier spine arrows i seem to be getting a right tear with my weaker spined arrows anyone else have this experience? I have always been under the impression that weak spine arrows will give nock left tear? Thanks ylfor your guys experience with this

Weak spine will typically tear left and occasionally will also produce a high tear.
What’s your bow setup and specs? And the arrows?

You probably have to have a good center shot to look exclusively at the tear for spine indication.

I've never heard a good explanation of how/why a weak arrow will tear nock left and a stiff arrow will tear nock right (for a right-handed shooter) out of a compound bow shot with a mechanical release. For a traditional bow shot with fingers, I can understand why a too weak or stiff arrow would cause a tear in a particular direction. For a compound bow not influenced by fingers on the string with a cut-out riser that allows the arrow to remain in line with the string path throughout the shot, I can't conceive of why an overly weak arrow would leave the bow nock left and an overly stiff arrow would leave nock right. I've played around with intentionally shooting significantly over and under-spined arrows (relative to what the charts recommend) out of various compounds and haven't witnessed these purported horizontal tear patterns. Arrow spine certainly can affect how a compound bow tunes (FWIW I believe the range of appropriate/acceptable spines is significantly wider than most people think), but I don't think the left tear = weak/right tear = stiff advice necessarily holds true.

A lot of times in my experience a weak spine just produces inconsistent results, with a compound and bareshafts/broadheads. You can get a weak spine to fly really well with fieldpoints.

The right/left stuff is for a stick bow that isn't cut past center.

can you drop the draw weight easily? Like 5 pounds. Not familiar with Solution weight changing. If not, try to add some weight to the tail of the arrow and see if that helps stiffen it up, if you already have a lot of weight up front. Wrap, Lighted Nock, etc.

Then something in your tune is off and not so much the spine.
