Re: Le Trap vs Angus MacKirk First Sluice. Randy, that is an excellent analysis. I have an A52 (now relegated to recirc duties), a Le Trap, Wolf Trap, Angus MacKirk and two Bazooka Gold Trap sluices. If I have enough water to make the fluid trap function on the BGT's I will use them; otherwise I use my Le Trap.
