Just as a footnote I have tried the SoprasSub Spider Fin and it had good speed but it has a problem when you kick off sideways because of the foot pocket to separate blade, you loose all sideways movement power.

So these are no good for hockey, if you live in Melbourne you can try them out if you want just contact me, luckily I didn't have to buy them as they were a sample given to me and I gave the manufacturer some feedback on them for our use.

cheers
