Ask away! Either PM or ask through the board, I may not find the question within the forum, deep in a post or something. As for shape I haven't really messed around with that to know the difference between the float vs. its function... for me, as long as it floats its good enough
igm, because the 'geen is so large, sometimes you would want to hero drift into ChaseChromes' hole from 100 meters away, in order to do so, I would buy the floats with the fat red heads... because you can see them from a mile away... rather than the small red tipped ones. So from that website I would buy the FD Fast/Deep ( see the larger red top? ) vs. the SM Shallow/Medium, little red top exposed, harder to see how it tracks down stream through Chases' hole
Some holes you may be fishing have a fast drop off and aren't really long... so bulk shotting is necessary to get within the strike zone... grab a couple packs of huge split shot... easier to put on 1 large shot than 10 little ones.
