The waves in the video are fine - actually REALLY fun to ride in these conditions IMO
Wind a bit sideon yes, and messy waves often, so not that pretty no - but there are really steep closing sections one can use for max "smack" and especially really high aerials are way easier to land in front of the wave
Quite normal conditions for all "open" coast spots I think.
And as Nico writes - you have to ride aggressively with the kite (but some like this also in sideshore conditions - personal liking simply)
My tip, mostly for those riding both frontside AND backside, like most of us do :
When riding frontside you have your trim in one position (the typical well known trim), but when riding backside you should trim the kite "down" a lot
Because, when riding waves you normally only have one hand on the bar, for obvious freedom reasons.
When riding frontside, you have your upper body and front arm in a position very far away from you, so the kite can be trimmed "well powered" and still be in the sweet quite depower spot that works in waves.
When you ride backside, this changes A LOT, as you still use the same hand on the bar, and twist your upper body towards the wave - but this means you can not reach far with your arm/hand, thus you NEED the kite to be depowered a lot, as you have no chance of doing this when backside
So by trimming the kite down, you get an extreme amount of freedom in your cutback and can lean a lot forward towards the waveface (inside the turn) - which is the "good" feel, and a must in order to make a snappy good cutback
This is not possible with a normal trim (unless you use the other hand crossed instead - possible yes but not natural IMO).
Whereas going frontside, you have way more options because of much higher "range" because your hand/arm has so much longer reach now.
This is not possible backside - but by trimming the kite down a lot, you will get an awesome cutback with no restrictions
The downside is the limited range of course - and you have to ride a lot with the bar fully towards you...
When the wind is a bit sideon, we often ride backside some of the time, if the waves are steep - as this often works better now.
When almost sideshore, frontside is the way to go IMO, as it will give so much more "kick ass" in the cutback, is our experience.
But sideon a mix between frontside and backside are used a lot, by many here (and me).
Hope above is understandable and can help some ?
