Unfortunately when you don't have lots of buddies whose fins you can try it is yeh. But you don't have to buy whole new fins each time, most fins (though not the gara's) have interchangeable footpockets so you can use the same blades but just buy new pockets, which at least saves a little money and you can sell the old pockets on here because there is always people with the same problem trying to find a match.
Maybe we should start a foot pocket swap shop
