Tail Pad / Deck Grip

Hey guys. I'm new to surfing. Had some lessons and enjoy it and it comes fairly handily to me. I recently bought a second hand 7' mini mal and was wondering if I need a tail pad. Would it help or just a waste of money for me? I've seen some say its a matter of preference but what do you all think? Dakine and Billabong pads are on sale half price at my local surf shop? For the sake of a few bucks. Could it be worth it? Thanks for your help.
