Cigar, IMO save yourself some time and trouble on your first attempt at float flying, Buy a set of foam core-balsa sheeted floats. After you see if you really like it and get some experiance at it, them go for your own set. There's a guy that post's here regularly that go's buy the handle of "SEAPLANE" aka Ralph Smith, he makes a awesome set for a great price.
Trust me on this........ Don't ask me how I know
