Alots going to depend on your budget.. I would say if your budget is big DSE would be the way to go. But If your looking for the best bang for your buck SpeedTech is the way to go hands down in my opinion. Very well made,installation should not be an issue. Take a look at how well Blake's Nova did at the Optima Challenge this year ,that should help answer some questions for you. Blake spends alot of time on this forum and I think thats great, He's never hard to find to answer any of your questions!!
