It's an illusion, I've taken a video of me clearing the trash, I'll put it up when I get it uploaded.

No. I just have the privilege of working with growers who between them own all the common disc drills. Without exception all of them will hair-pin chopped straw. I see it every year. Even found the same in France last autumn.
I had loads of hairpinning planting the osr last year.
Not had any in bean stubbles, osr stubbles, linseed stubbles, grass leys.
Cover crop residue.
That's the osr field that had the worst hairpinning, 2.4 kg/ha seed.
Looks fine to me.
Some of them have oportunity to push disc deeper and seed boat adjust at normal drilling depth...

But the effect is the same. Decaying straw below the seed prunes the roots. So restricted root growth.
I dont agree...

Lots of experience with both single & double disc openers here, but just wondering, why "chop" the straw. Surely that makes any residue handling problems worse by leaving a thick layer or loose material you then have to slice through ?
Why not leave the stubble standing & plant straight into it ?
Would make harvesting quicker & cheaper as well . . .

I am intending to cut higher this season. Wherever possible anyway.
I'm wondering if sowing up the exact same row would be a good idea or not.
I'm on rtk so should be possible.
There would only be standing stubble for the disc to contend with on the whole, the chopped residue should be on the ground in between I think.

Depending on your row spacing, it is common practice here with RTK to sow between last years rows . . .
Although, there is also the theory that sowing on last years is better . . .

There is still some straw in the slot. Whether or not a bit causes a problem is another matter.

Drilling grass seed last autumn established well baled straw
Drilled over 5000 acres with a 9 m gd on the original set of discs and bearings Which we changed this spring
More than double the area a fixed angled disc and bearings will do
Because the disc follows the line of least resistance the power requirement is much reduced compared to a Moore or big disc
Now Run a 260 cvt t7 which show 45 to 50% power usage at. 21 litres per hour fuel 8 km per hour
I Always prefer to have a wider drill slower than a narrow drill quicker gives a better finish with lower wheeling
When conditions are dry and hard after beans or stoney fields slower speeds give better establishment

The only straw in the slot is the remains of the oat plants that have been cut through and one bit of straw that I pulled out the slot. The rest of the straw residue is on top of the soil.
I do intend cutting higher this year to make straw less of an issue as there was lots of hairpinning last year drilling the osr, hasn't affected it's establishment but I didn't like it.

I cut as high as I can leaving a long stubble
Increases combine capacity
I would like to try spreading unchoped straw as we used to do for burning
One year had to plough a field that was just spread with a set of skimmers with discs this was not a problem
I find a mat of fine chopped straw is worse than long stubble
The need for fine chopping is for cultivation and brakedown improvement
Hair-pining is more a problem in softer fluffy soil when a sharp curt is not easy

For zero till ground cover is good. More ground cover is better. Bare ground is bad.
Weeds find their way through trash, so crops will as well

Leave the straw standing, much easier to deal with
I agree in dry conditions yes but in the wet we get in the western area of the UK on heavy soils it's a disaster,For zero till ground cover is good. More ground cover is better. Bare ground is bad.
