Regluing

Is regluing really necessary? But some says if you dont, the rubber will go "dead" and wont have much spin. I dont play on a daily basis, maybe 2-3 times a week. I've seen others reglue every single time they play. And they play almost everyday! Wont that be a hassle? To tear off rubber on and off. Wouldnt that damage the rubber/sponge? On top of that, they buy new ones(rubber) on a monthly basis! Geez..Personally, I really dont think its necessary but still I very much want to maintain them in proper condition. Both my FH/BH rubbers arent that cheap but if high maintenance is required, I'd rather get more economical effective rubbers nextime. Least it wont hurt much everytime it goes "dead"..
