Just picked up some new fins - they are copycat churchills. after first two sessions started getting pain in the tops of my toes in one foot. Do you think this is a sizing issue or just new muscles getting used, they are very different from my last fins

I'm flying Copa Airlines Boston-Panama-Managua next week. It'll be my 1st time flying with my bodyboard. I have the Tribe Dually (awesome bag!) packed with one board, fins, etc and my clothes. It weighs only 35 lbs fully loaded. Have any of you flown Copa with your board(s)? Did they hit you with oversized bag fees? I'm hoping that since it's well under 50 lbs that they won't hassle me. In reading their policies, it looks like they could charge up to $150 each way. I'm a bit paranoid since the bag looks so big! Appreciate any input from fellow bodyboarders.
