thanks for all the complements guys, i put alot of work into this batch - and it really paid off
ROC, i turned them on a lathe with a duplicator. the top ones do have a flat on the top....that's what makes them a deep diving danny. the water will help force the plug down.
i'll take you up on that offer AH. I swam them today after work just before the sun went down on me. the had a good, tight wiggle to them. with faster reeling - or a few tugs they disappeared.....when i slacked up on them they came back up, but sloooowly
I should've done 1 or 2 with the lip flush to compare

I did that on the last (black) one, but that has a small lefty lip.
