I'm glad you used my correct name there - My wife hates calling me God all the time
You are right that experience in the sport, doesn't equal experience with testing new equipment.
But when you are arguing with experienced people, on a forum where they have been commenting on equipment, using equipment, and generally helping others in a considered way....... Well..... You'll always come across worse.
Like I said, I'm not trying to knock you for your passion - It's great. I doubt anyone on this forum is perfect. When I watch videos of me messing around, there are things I know I can improve on, and I'm sure others (both new to the game, and experienced players), could probably comment on as well (stand closer to the table) has always been my weak point!
It doesn't help that there is no "unified" rankings list or anything - The US way of rating players is different to the UK, which is different to Europe etc - So it's not easy to quickly see where someone is (in terms of their ability).
Whether you like it or not, ability plays an important part when taking (or giving) advice.
If I read someone say "This rubber is terrible, I can't hit a backhand at all because the sponge is too hard" - But then I found out they had a terrible backhand, or hadn't played with many different rubbers, would I bother taking in their comment?
No...... No I wouldn't.
So like I said, don't stop improving, but try and be a little more measured when discussing table tennis equipment (and giving advice), because whilst you may mean well, you could end up causing more harm than good.
If you disagree with someone, it's best to try and find out more about their experience with whatever it is you disagree on.
Thank you for posting the videos and showing your progress - It's great to see.
You should let us all know what you think of Karis when you try it - Perhaps record some video of your training session with it?!
