The Clunn models, like all the rest, need to be float tested in a vat of ice water before going out to the lake. The ones I have bought all needed some degree of weighting to suspend. Of course florocarbon vs. mono is another factor in the suspension of jerkbaits.
Upon very careful examination, the bill of the Clunn model is slightly smaller than the 110 (Wish it was slightly larger) so it tends to run about 6-12 inches shallower. Still, it's well worth 1/3 of the price of the 110. The three extra birdshot that Megabass puts in their 110 must account for the $18 price difference! LOL
