It seem you confirmed my doubts. I previously ride on falcon 144 and jag 125 and it was so wrong to ride slalom boards. Blast is pure joy considering my intermediate level. I am cofident in waterstart, straps, harness, speed, tack, but jibe is something I need to work on. Except ride, Blast is also much more intuitive for jibing comparing slalom boards. I will use Blast 145 between 15 to 25 kts with 9.3, 8.3 and 7.3 S-pace while I would like to take smaller Blast for 25 to 35 kts condition with 7.3 and 6.6 sails. Over 35 kts will be really rear conditions!
It seems due to my size 130 would be better choice even it looks to close to my 145 board. Please advice
