I searched for similar threads but didn't quite find one that suited my question.
I'm 87kg (I do a lot of gym and running) and wanted to buy a slalom board. My main interest in windsurfing are waves but when the wind is light I like to jump on a slalom kit some time and due to the really bad season for waves this year on my homespot I wanted to buy some slalom equipment for myself to be able to sail in weaker winds.
I already have a good boom and mast (460) as my brother rarely uses his kit so I use it more often and I wanted to make a low cost kit with just buying a slalom board and sail (with 460 mast the choice would be probably 7.8 as 8.6 requires 490).
My main concerns are:
1. What board should I buy to sail in flat/choppy/wavy (sometimes) conditions with 7.8 sail considering my weight (87kg)?
2. What range could I get from 7.8 paired with 107 iSonic, 117 iSonic and iSonic 117 wide? I mean what could be the smallest wind for me to get plaining in (knots)? I think that I have enough experience to handle the kit as this is my 13th season and I already tried some slalom and formula kits before and I really liked it. I also sailed a lot in light winds on bigger kits (also freeride rigs).
3. What fin should I chose for the board that would suit the 7.8?
4.Maybe I should buy a carbon mast extender and go for a bigger sail? (however the mast I have is X6 80% carbon (low cost option is the only option for me as mentioned before)? Will the carbon extender work anyhow with 80% carbon mast anyway?
5. Maybe some older model like the iSonic 122 would be ok for me with 7.8 (it would also be cheaper)?
Sorry for so many questions
