I have straight cut gears, and in all honesty, first is a little noisy, but seccond is nearly silent most of the time and i think rebuilding the gearbox is a good option. I kind of wish i went for dog engagement to make driving more interesting, but the ppg gear sets seem quite good.

If you have the money then go for the 6 speed but i do feel the 5 speed has it's applications.
