The problem with the T-8 isn't the top end overall OFF++ speed. Problem isn't weight or balance, blade is HEAVY solid (good) and balance is low enough.
Problem is... Loopers need some dwell to feel the ball and spin it up for control. most attackers are 2x inverted flexible OFF players who live on creating topspin to control their offense. The ball comes off the bat in too short a time to make positive control on most loops. This forces you to open the blade and hit through the ball. There is nothing inherently wrong with that, in fact, that is the old-school style of playing. Problem is the lack of dwell time makes It darned difficult to play a dynamic topspin attacking game.
This blade forces you to HIT, so it is VERY suitable for those pips out hitters, and those who really like a fast loop (loopdrive) (Koreans call it speed drive) as their main weapon of attack. Most dynamic flexible attackers need a wider variety of possible effective shots than just a loopdrive, a very flat drive, and a smash. Player who use mostly ONLY these shots, like typical old-school Koreans, will simply LOVE this blade. In fact, it seems a very LARGE portion of the amature crowd uses a similar class blade... the Schlager Carbon.
Another class of players who crave such a blade are the OX LP punch blocking crowd. They need a fast/solid/stiff blade to maximize spin continuation (reversal). They bump knuckle medium fast and aggressively punch underspin. On FH, all they do is push underspin or power slap at the ball. A soldi OFF+ blade with a control rubber on FH is perfect for that style.
That is why you see nearly 100% of the Over 40 and Over 50 ladies crowd who are OX LP BH players use a Schlager Carbon with a control rubber on FH and Grass D-Techs on BH. it is almost a standard prescription by coaches for this style of player. If you line up 25 of these players, you will see 23 of them with a Schlager Carbon, 1 with a Gergely, and 1 who is independent and uses an oddball blade.
So... the T-8 isn't necessarily a terrible blade, it could be very suitable for several styles of players, but certainly not the most efficient blade for a modern dynamic 2 wing flexible attacking game. just too short of a dwell time to really control the ball for the strokes needed to play like that... and the overwhelming majority aspire to play such a modern flexible topspin attacking game.
