yeah, I always prefer a 1/4 (ours still is a 1/4 most days).... but ... getting more and more half-tracks. It's about 6 hours and about 75 - 100 bucks on a Saturday for me. Hour down, hour back, gas round trip and at the strip, a meal for my wife and I, entry fee. It's why many want me to make one change at a time and take it down per item, but it's just not realistic (i get their point though). I'm forced to trust my seat dyno over a few changes then take the car/truck down and see where we are...
