Like stated above it does help prevent transmission breakages when you shift hard. Bending or breaking a shift fork will happen within a few powershifts. As far as helping you run a quicker time, no not really, but once you adjust to it you will think it's money well spent. Nothings more frustrating then missing a gear. And missing gears can be rough on your drivetrain, especially when valves float with no load on the motor. I use a pro 5.0 and driven a steeda tri ax. I liked both, but the steeda comes with a longer handle so it's a little easier to drive imo. What pissed me off though was MGW came out with their shifter just a couple months after I got mine, and thats what I really wanted. Oh well. Just stick with Pro 5.0/Steeda tri-ax/MGW (ftw imo) and you'll be good. Just be sure you set your stops properly and tighten the s*it out of em. Myn would work their way loose when I didn't tighten them that much and it would pop out of gear. Losing 1st, 3rd, and 5th while driving isn't fun at all.
