I used to think the same way. I don't any more.
For Singles play, young kids need to develop "weapons" as soon as possible. That means a Big Serve, and a Big Forehand, and great court movement. The "variety" shots can be developed later on as an addition to the weapons as required
Without weapons, the player's ceiling is limited. That is fine if the player doesn't aspire to play at really high levels. But for any player that does, weapons are the key. If the player doesn't have a huge serve and a huge forehand by the time they are 18yo, they are unlikely to get to Professional Level. (And don't get me started with the Mental side of the game!)
And for players who aspire to very high levels, winning every match is important? Why? The more successful the player is early on, the more attention they will attract from organisations and people that can smooth their path to the higher levels of the sport. The only caveat here is that player's appreciate the value of the odd loss in that a loss is not a failure but a learning experience. Junior players that "get that" will go a long way.
And ... the smartest players understand that they never "Peak". Even Roger Federer continues to work on improving his game. That is a great lesson for all of us.
Back OT, full beds of poly string will enhance the potency of the weapons.
I agree, a full bed of poly gives pop - but not sure if it creates weapons for 11 year olds that a hybrid can't. I would blame technique if that is the case. I don't believe you can take feel out of the game if you want to be a good player - it's too important. It can also help kids feel more confident in certain shots. Also, if you aren't old enough to swing a heavier racquet, then you can do damage to your arm. Why? Because lighter racquets can cause arm issues AND poly is another element that can cause arm issues. Also, the kids that are at the top at 11 are usually not the kids at the top in the 16s - with a few exceptions of course. I'm just saying 11 is too young IMO - 13 is more like it. I've coached my son (17) to the national level and he will be playing in college next year. Not saying I'm right, but it's worked for me.
