Ok.. I just bought the Volo Power (got them at a good discount) and am now wondering if I made a mistake. I have been using the Avanti Quarttros and SP Jets for the last 10 yrs and have developed a finning style that is part flutter/part frog (depending in situation). Some reviews say that the Volo is able to do both competently and will more ease (I am getting older). I would like some real life experience with this pair of fins. Comparisons with Force Fins are welcome (I junked a pair about 6yrs ago, worked well with flutter but little else).
