I bought 2013 blades in 4.7 5.3 6.2
The wind range on the 6.2 is fantastic The times it was a handful I changed down to my 5.3 and was even still overpowered on the 5.3 I would say that when comfortably powered up on a 5.0 blade I would be overpowered on the 6.2 The 6.2 doesn't really feel that big to use, the boom length feels fine in the waves.
Yes less brain power. Other guys chugging on 5.3 5.5 5.7's then me go the 6.2 others whizzing around on 5.0 5.3 then me go the 5.3
6.2 definitely increased my Fun and TOW
