I have never played with a 1cm increase but you guys with ur arguements made me wanna test it. My guess/prediction is that NL is spot on about the rallies (slower pace/quality) , but baal and suga have some interesting points too.
Ill try to be quick.
Do we want longer rallies? I think yes because fans will enjoy the game more
Does a 1cm height addition guarantees that? Uhmm probably yes , but ignorant fans out of the sport will still find it hard to spectate and understand the whole serve/receive tactics/sorcery. Different camera angles could do a job. If you watch some 2016 full CTTSL matches, they sometimes switch for 1-2 seconds to a camera that clearly shows the contact point of the server and then immediately switch to full table mode. Ignorant fans will still ahve a hard time understanding sidetop or sideunderspin serves, but I found these camera views really exciting
Are pips/defenders in disadvantage? Please dont start throwing tomatoes at me, my viewpoint of the game is that pips and defenders were always at a theoretical/statistical disadvantage because of their limited style of play (im talking speed glue era and after, I dont know much about the previous years). Destroying your opponent's game is a strategy yes but if the opponent adapts its simply game over. A top looper will win 7-8/10 times against a top defender , regarding all the other factors the same.
I think the issue is purely psychological, Gionis didnt like the new balls at all and thought his game would be destroyed at first but after 2 years, he feels quite good and finally adapted (is it unfair compared to a looper, yes it is but we cant have it all can we??) . That are not my words but his words. Examining pips player again but this time short attacking, I dont think mattias karlsson for example will have a huge problem if the net increases. Probably will find it more difficult than attackers to adapt, some bad results after the change but in the end he will still be a beast of a player
Another assumption I made while I was reading you guys is that we wont have so many attacking banana flicks in the game(at least not at the current speed of execution), which will prolong the rally even more. The strokes will be a bit more vertical, thus more arc, thus more time for the opponent to react
The serve receive & opening phase will be also tricky, I cant imagine how short push after short push will affect the game, Im guessing that pushes will be less spinny or with a bit different technique (a bit bigger stroke maybe to pass it over the increased net height) . This also affects the recovery of a player after a short push/flick to quickly get into ready position for the next ball. I dont know all this is pure theory, If i find a willing partner and have a camera I will try it out
Cheers
