I went pull start on mine
Had a roto start on all my nitros, but it caused me some issues (broke a con-ron on my k4.6 when it hydro-locked, and I couldn't stop it cause the damn thing got stuck on), also always having to have the battery charged I found was a hassle or when the roto start would crap out when I was out and end my running(happened a few times).
Pull start if I take my 3 nitros with me I don't have to worry about them not working
