Might be interested sent you a pmanyone want to buy a set of hardly used 16mtr sk99 1.5 mm lines before i put them on Ebay?
Seriously, I can't see a 5m Peak4 working below 10 knots, I have only tested a 4m Peak4 and ordered myself a 5 & 3m on the back of this test, if so I'll be selling my 10m Soula Peak4 3m and 5m kite for the average weight foiler will cover from 6-7 knots to over 25knots
