do you guys think that heel guards are really necessary? The nerfs with no heel guards or foot pegs are about 125$ cheaper, so im thinking of just buying those. The ac propegs with the heelguards sure are nice, just dont feel like spending that much money. I can get the ac regular nerfs just 130$ or the propegs with nerfs for about 250. I dont race, but all I ride is track, with the occasional trail ride. Think these regular nerfs will be alright, or should I invest more money and get the propegs with nerfs?
