not a problem man. like i said, i have both but when it comes down to it i wish i spent my money on the spray first. yes it may be more money to fill it. but when it comes to power. the meth isnt anything special. you wont feel it kick in like nitrous. and put it this way, blue washer fluid is for cleaning bugs and dirt off your windshield, can you imagine what it does to your motor? not a bad way to burn a hole in your piston. with the nitrous all your gonna do is put out the flame, stall the motor. its your truck and you call either way. I just figured since ive been there with both products i would give my 2 cents in the matter. if your gonna race the truck, either on the track or the street then nitrous isnt too costly. you can get about a night outta the bottle. I dont play around on the streets. so for me to fill the bottle and shave some serious time off my 1/4 time its worth it. Look into both first and then make your decision, look into the snow stage 3 with the controller, very easy to use and works great. hope everything works out for you!
