Welcome back! It’s always good to have someone picking up a yoyo again. ;D
The swivel tension thing seems like a great idea, but I’m not sure it’ll catch on in general play. Modding yoyos isnt as big as it used to be and 1A has already come so far without swivels that I can’t see them being adopted in normal play. Also a lot of people compete nowadays and they are as yet not allowed in contests that I’m aware of.
As far as when all modern yoyo advances came about, I’ll be expecting Kyo, Yoyodoc or Steve Brown to come in with a sensational date-by-date account of when it all happened. In the meantime here’s a little history on unresponsive play to start:
There’s a quote from André on one of the ‘learn’ pages of YYE, and below is a great post from Yossarian, a forum member:
…and one from Nathan, who is a professional player:
I hope these answer the question as far as modern unresponsive play goes.
In recent years the design of yoyos has changed from the more undersized, mid/high walled organic throws of the mid- 2000’s like the YYF 888:

To the larger, more rim-weighted, low walled steep V shapes prominent in most of today’s modern throws:
With the addition of a lot more horizontal play, the lower walls of the yoyo make life a lot easier. Also the performance is a tad better for today’s crazily long tech freestyles.
Even more recently there has been an up-surge in the popularity of horizontal finger spins, pushing a lot of recent designs to incorporate a design that assists in this move, like the Yoyofactory Horizon, Eternal Throw Elysian, Duncan Strix and many more.
Recently again, there has also been a seeming increase in the amount of bi-metal yoyos being produced. It seems to me that this is going to be the next big thing as far as yoyo design evolution goes. I know it’s been around for years, but it seems to be really taking off in recent times.
Don’t worry, I tried and gave up yoyoing when I was about 15/16 as well, and only picked it up last year at 23. Still, with enough practice it shouldn’t take you too long to catch up with the rest of today’s yoyoers, so keep at it. Welcome once again to the community.
