Rolling Thunder Game Calls Two Stroke Features The Rolling Thunder Game Call Two Stroke is built around a keyhole cutdown tone board the same design used on the Original call which gives it a proven raspy cutdown voice. Running two 0.10 mil reeds instead of a single reed setup makes this call noticeably easier to blow which helps newer callers find consistent tone faster. Despite the simplified operation the double reed configuration retains the volume and range hunters rely on to reach working ducks at distance. This balance of ease of use and performance is why Rolling Thunder markets the Two Stroke as its most popular double reed option. The call body is turned from Frost acrylic a material chosen for its durability and clear resonant tone compared to wood. Acrylic calls also hold up better in wet duck blind conditions where moisture and temperature swings can affect a wood call s sound over a season. The Frost finish gives the call a distinct look on the lanyard while keeping the same reliable double reed system inside. For hunters who want a dependable easy blowing duck call for the blind the Two Stroke in Frost acrylic is a solid choice.
