Last year we went in late June early July. Not much rain, not really that humid. (not like Florida!!!) It was 85-90 most days .... but didn't cool off much at night. Where our house was we always had a nice breeze off the ocean which helped allot! I enjoyed it!
looking at the hook, it does have a wide gap. I would guess that the problem is lessened with larger dumb bell eyes vs beadchain? I've used this hook for epoxy bait fish and such. Where the hook is in normal attitude. In that pattern the hook works great as a keel. Interesting observation on the inverted tie.... I never thought about that problem. Will have to check it out!
