I have an SC10 and a Blitz while my neighbor has a Strike..Forget about the Strike as it is very fragile. The Blitz is very tough and with time and people tuning it, it will be a decent racer. The SC10 is a lot better than both for racing. It is also very durable, but not to the extent of the Blitz. If you want to be a pioneer, get the Blitz as you will be hard pressed to find proven set-ups for it. With the SC10 there is a ton of information already out on dialing in the hot set-up. My SC10 is so dialed that it's impossible not to go fast with it. My Blitz has some work to be done before I can say that.
