Thanks Monte for the heads up on the 7x4 coil. Was also considering the 7'' concentric. I might just wait and try out Ryans Anfibio before buying. Nel just came out with a 9x5 for the Anfibio/Kruzer. Im sure the snake won't be long after. Ive always like the way the nel coils ran on all my other Nok/Mak products. Might be worth the wait.
check it out.
