Hi Andy, cool, nice to hear you are progressing so well, just back from a 6am session at Tegernsee this morning, always fun!! So I am using the Free 1250 and 1000 mostly on flat water. Carve 900 or 750 in the waves or when very choppy and top end speed is not that important. Sounds to me like maybe a 750 Carve and 1000 Free could be your perfect setup for all wing sizes, you will never use the 1500 again at your weight/the level you already have. for 65kg I don't think you need the 1250 either, I rarely use it, even this morning it was super light and I can still get up and go with 1000Free and 6.0 Unit. Hope that helps, cu on the water, Sunday looks good at Worthsee...ps quite a few of the locals/friends are loving the Free 1000 and 1250 here...
