I am about to purchase a pair of Scubapro Jetfins and I was wondering if I should get the Large or XL. I recently tried out the Larges and I was pretty happy with them. I am just wondering if I will be sending them back for XL's a week after I buy them. I am 5'5" tall, 160 lbs. and my shoe size is 8. Do you reccommend L or XL?
