I liked the original remix by Rodney, but it was "quite pointy in parts" so I rounded it off a bit. It is now more comfortable in the pocket and works just the same. This remix is not as loud as the V29 but takes up dramatically less room and functions as a sort of two in one. If you blow more gently you get a more quiet whistle like a ref whistle without the pea. If you blow harder you get an extremely loud piercing tone.
