Tomo Fujita Guitar Wisdom

I found a course a while ago to play a Jimi Hendrix song where I was then gripping the guitar neck to play thumb over chords. Been playing it a lot. SRV grip.
I was watching a video from Tom Quayle on correct hand position - C shape like a dead spider and I realised I had been playing a lot of lead guitar gripping the guitar neck like a baseball with my thumb over and not at all in this C shape / dead spider. It had crept into my playing... then I remember my old guitar teacher who had said to play the way Tom did, but I had forgotten.

And Tomo talks a lot about the thumb and wrist too. So is gripping wrong?

I have been having a lot of pain in my wrist and I wonder if this is the reason? I know I have a weak wrist as I have been operated many years ago for carpel tunnel on both wrists.

So the question is.. which is better technique? Or easier for the wrist?
If Hendrix is a wrist killer then I’ll give up on that.

For bending ,yes we grip, but single notes I realised I am gripping too and shaking hands with the guitar,

Appreciate all inputs.

Thanks

EDIT: just rewatched lesson 3 and I guess in some ways it answers my own question.. injury free playing softer and smoother... still, any experience out there I would appreciate to hear.
Think I have to give up those Hendrix chords lol

Another thing you might want to also consider is the fret radius and neck profile.
Years ago, I had a couple of Ibanez RG series with thin wizard neck and 16 radius. It was my dream guitar and I used them for a while but my wrist also started hurting after a year of playing. It was good with soloing but not for Hendrix style playing because I had to pretty much bend my thumb 90 degrees to fret the E and A strings. Then I got to try a Richie Kotzen Tele and though it was way too thick for my hand, my thumb was more relaxed and with a 12 radius, thumb was able to wrap on the top 2 strings a little better. I finally found that a deep C profile with 9.25 to 10' radius was the most comfortable for my hand. I recommend trying out different radius and neck profile until you find the best one for you.
Also, if you have history of carpal tunnel syndrome you do want to regularly stretch your flexor tendons including the lumbricals even if you had a carpal tunnel release (I'm assuming that was the procedure done) just to make sure the long tendons are gliding freely through the wrist tunnel. After the release, there is a chance that scar tissue will develop in the area where the ligament was cut; those scar tissues stick to everything - moving and non moving structures in the wrist/hand and this could lead to adhesion or another carpal tunnel syndrome. It's an easy self stretch that you can do. You can find video demonstration on youtube if you search for finger flexor and lumbrical stretching. When you do the stretches, make sure your elbow is straight because the long flexor tendons cross the elbow joint as well.
