Hi
Hi Waterlover I agree with you in something you are using the logic - but not agree not at all
we can have big feet but with a bad stroke- is like nothing it will not help you much
Do you know how many stroke david does in dinaminc not fins in pool? 3 stroke- Im 6-2 and still Im working hard to do 4 stroke for the 25 m dinamic not fins--
what do I really need to do 4stroke?? well-- nothing to do with my hight-- but with my stroke- or body positiong-
supose you are a beginer - and you are a very tall guy - how many stroke it will take you -- maybe 9 - 8 -7
di you understand ?
big feet can be good-in part - but - is only one component--- of what we really need to get deep--
also--- we can be tall--- but if there is not a good streamline while swimming is like nothing--- the taller you are in this case will not help you much
____________
Now talking about

shave short fins you can go less deep than if you have long)
Im not really sure in this but--
what make us to go deep is the -weight we use-the capacity we have- more thant the fins--- not sure but I think is not necesary to use the fins a lot-- CORRET ME IN THIS-
Now - I think we use the fins more when going to the surface--
in this case- LONG FINS- Will help us A LOT--
Im right or not ?
just my opinion
Daniel.
