Do you mind if I ask what you did which restricts your ability to mixed grip? In terms of loading, I would expect your back to be loaded in a similar manner irrespective of the hand position.
Not who you asked but I use overhand hook grip and do conventional deadlifts (not sumo). I find mixed grip bothers my bicep on the underhand side. I also use chalk, and straps for heavy pulls.
I don't understand a gym that doesn't allow chalk.
somehow mixed grip makes me twist slightly which caused me back problems; after a few tweaks to the lower back, I decided that mixed wasn't worth it (I don't compete anymore). Yes, you are right, I do use the hook grip, since I also do some weightlifting.
It's worth noting that sometimes (incorrect) keyboard maps can get in the way.
If it's a key that you may not often type and one that is often transposed between regions, the fact that the entered char is not shown can lead to frustration.
e.g. " and @ are in different positions in UK vs. US keyboards. So user thinks they are typing @, but " goes into the box.
One of the more annoying things I've found moving country is the unavailability of keyboards / laptops with the layout I grew up with. I find it especially annoying as the country I'm from uses a US layout which I naively assumed would be easily available everywhere (and it is available but not without a long delivery and a premium price)
Side note: helping my French housemate with his uni assignments was an experience, none of the symbols were where I expected them to be
Meh, takes you like some days to get used to another layout being visible on the keys, while your OS (and brain) actually using another layout.
I've used US keyboard layout since I started programming (my first mentor essentially forced me to switch to it, he was right about it being easier), but throughout the years been using Swedish, Norwegian, British, Spanish and French physical keyboards, never cleanly mapped to the actual layout I've used on the OS, and never been an issue.
The last part though, is a real one, trying to pair program with Spanish programmers always have at least one moment of holding Shift and sliding the finger across all numbers to see where that specific symbol actually is.
On other layouts that isn't enough. For example French keyboards are AZERTY, not QWERTY. and here in Sweden we have å, ä and ö next to the (tall) enter key, instead of the symbols US and UK have.
(Side note: those are not a and o with diacretics, they are entirely separate letters in the alphabets of the Nordic countries, with entirely different sounds.)
The product I make deals with passwords. We’ve had several bugs over the years that came down to Unicode usernames and passwords containing unexpected characters. Solving them was simple, we just had to be sure to get the encoding and character sets right, but as an American it was eye opening to find so many people with the Euro symbol in password strings.
Related, a friend of mine uses a long list of heavy metal band names as one of his unit tests for strings. Says it catches a lot of weird encoding bugs.
Pure Silicon Crystals for the wafer is another very specialist supplier you can't just decide to become - your local gravity will probably have an effect you need to tune into
I assume you've considered/use hook grip?
