T' wind was really blowin' hard and I went t' me only rocket I had with me that had a streamer. Plus, tube fins tend t' deal well with t' wind. It did indeed put up a great flight. Altitude was really high for a B4. Begad! Blimey! Would have been even higher with a 6-second delay. Blimey! Blimey! It was about out o' gas when it deployed but be still goin' up. Streamer did t' trick and I had a fairly short walk for retreival.
