My first tour, Torpex's were 75% dropping extorps on sleds and 25% dropping them on subs. Sometimes you got luck and the extorp's turnaway feature failed. Then you got to hear the thump of the extorp hitting the sub. I dropped on subs twice and was lucky once.Ah, the old days when runners were common on the range..
Mostly dropping logs the last 3 times I went..
6 weeks on Andros Island is 4 weeks too long.
My DH tour, everyone was amazed when I talked about dropping on subs. It was all sleds.
