Kendama weight is a topic that might have been discussed a lot. But I have an issue and am after your thoughts guys and opinions to stop my disappointment and reduce my loss of money on so many kendamas in a short time

The story
I have had communications with many kendama suppliers, I have dealt with at least 4 Kendama online shops, I have made lots of research, I have been playing for couple of months and I came to conclusion, this game is spreading and the online shops are destroying the reputation of the game by not being honest, not cooperative and sometimes misleading.
Sorry for this introduction, however I consider you as one of the VERY cooperative and informative team. I am reaching out for you for information based on which I will make a purchase that hopefully does not disappoint me after all. and it should be very soon.

.
I am after a certain weight according to my short experience. I have owned Kaizen Zebra, Krom X Autumn, Ozora Keyaki and KROM deluxe walnut the cross
Kaizen was my first kendama and bought it just for the look and i don't like how it plays, it is very light, it came already chipped, unbalanced and did not break in so I just left it.
KROM X Autumn (major disappointment, the tama 70g and the ken 78g, makes cup tricks very difficult for me, and the tama seems not to be completely round since it wobbles on landing on cup), it might be good for balance tricks that require tama grip though.
Ozora Keyaki ( I just seem that I love natty's). I read a lot of good reviews about it. when I received it with big expectations, however I was also disappointed with a 80g tama and 68g ken (12 g difference) and it seems like it will never break in, this killed my joy, but it opened my eyes on the weight thing since it is heavy, at it was the most one that I could easily do cup tricks with and it improved my moshe kame though it became tiring

, for some reason earth-turns are difficult with it and the bird is extremely difficult.
The KROM walnut the cross, disappointed again, Very light (Small tama smaller than others) 70 g tama with 62g ken (Balance tricks are very difficult most probably due to the light ken).
After trying all these I have come to prefer heavier tamas since they make cup tricks alot easier due to weight but not 80 gs, I believe 75g would be ideal. I liked the Ozora ken shape more among all. I would prefer a ken that is little lighter than the tama to help the tama settle on the cup due to weight difference (not more than 5g however).
After all this, I am after a kendama that has a 75g Tama, 70g Ken (there should be some stores where we chose the weight we prefer, right?) breaks in nicely and really durable and playable for cup tricks and balance tricks, I am following TKA international tests and wanna go for Dan 1 and Dan 2 before i start free styling to start on solid basis.
I would appreciate your thoughts and recommendations from the experience you I have paid lots of money with lots of frustration, (Exchange is not an option for me being international customer , cost wise since I will bear shipping costs).
Thanks All

I really appreciate you taking the time to read this long "may be boring" query and thanks in advance for your valuable advise.
