I don't knuckle the ball, have no tearing, and have no need to use Hada tape for protection. I do however sometimes use Hada tape to just to snug up the thumb. 
 
For whatever reason, the tape doesn't always stick well, even prepping my thumb with an alcohol wipe. It's the nature of different skin types. I've seen this with others who are very good bowlers and otherwise exit cleanly. 
 
Someone here mentioned a while back that prepping with Benzoin Tincture will do the trick, regardless of skin type. I bought a small bottle and the stuff is magic. You can get it cheap on Amazon if you need additional stick on the thumb.

That's ironic. I originally had trouble with Hada tape and was recommended the Benzoin tincture. While it helped, what helped more was going to the individually cut strips (vs the whole tape which you had ot cut into pieces yourself.) I think the individual pieces used a different glue. Currently I use both Hada (Vise brand) and Turbo Skin Protection Fitting Tape.
Neither come off my thumb.

I originally used it to help with my thumb release, but it has protected my thumb so much that I have virtually no calluses on my right thumb at all. If  bowler looked at my hand without knowing who I was or what I did, he'd never suspect I was a bowler. (Some people say that anyway, but that's another problem. )

Hada has become a mask for some not all but some.  More and more use it and that is very telling. 

I see very few pro's on tour use it....hmmmmm food for thought.

I'm mostly in agreement. There are certainly some bowlers who use Hada tape to mask problems with span, pitches or whatever.
 
I personally use nothing on the thumb about 70% of the time. It's only when I'd rather not add another piece to the front that I'll apply thumb tape on the back. The Master Momentum tape is especially good for this purpose. 
 
As far as pros, don't underestimate the number who apply some protection, even if it's not tape. One day in the paddock at the Senior US Open last year, Norm Duke was frantically asking around for skin patch that he had run out of. There were several others I saw, across the different squads, who applied patch ahead of time. Bowling lots and lots of games over several successive days can be a whole different thing.

You might also want to "round out" your pushaway a little. Extending the pushaway
until the elbow locks will often make you top heavy. This results in the feet chasing the ball. It causes bowlers to over-accelerate step # 3 (for  5-steppers). This will often
result in the ball feeling suddenly much heavier ( causing a slingshot effect on the downswing). In turn, a bowler will actually attempt to grab the ball harder in order
NOT to drop it. Unfortunately, there aren't that many folks who have strong enough wrists to be able to hold onto the ball .  Rounding out the pushaway motion keeps your center of gravity centered under your legs, and it results in less grip pressure being needed throughout the swing cycle. This, along with a properly fitted ball, will minimize
 those early "dropsies" at release and your swing timing will be more in sync with your feet.  It takes some time and patience because it will feel different at first, but this is true with any change.

Otherwise, your overall game looks really good!

Best of luck to you.

He got very good advice by the looks of his form.

Tape is NOT a crutch...if you actually believe you have digits that NEVER change in size due to atmospheric changes or salt content...well some may have minimal change in their size in the grip but tape is NOT a crutch...nor is wrist support...the wrists and ankles are the weakest joints in the body...thus why they're called supports
Not everyone is gifted with incredible natural abilities...and others that feel they are shouldn't chastise those that don't

What's the address to your Proshop? Maybe you can check my span and give me a few tips too coach. I will travel. i sure need some help, and learning from an Internet sensation like yourself will be an honor.

 
He's suffering from a terminal case of bitter bowler syndrome. Don't read anything more into his posts. 

It's funny how many guys that do NOT have actual pro shops on here or any other social media sites come across as fricking knowledgeable...
