These are good rubbers. Mendo is a fine allround rubber. I've used Mendo MP and it has a superior performance and i never glued it. Many people say Mendo MP is the best mendo out there. But i never compare it with Mendo Energy. Give it a try
every player should have not only one serve style.. In my opinion,pendulum is the best serve as an attack opening/dominate the game, and the other serves are just variation
just try to use blocker player's equipment like Vladimir Samsonov(Tibhar samsonov alpha) or Oh Sang eun(bty Petr Korbel)... maybe it will be a worth try
