Hi Max
just checking to be sure that you are aware that there are two models in the Trident full carbon range? Apologies if you already know this information.
the 'Ultra' is the small spade;
Blade length 369 mm
width 177 mm
volume 0.2 ltr (very important for pulling power)
(left paddle in photo)
the larger one is the 'Elite'
length 433 mm
width 192 mm
volume 0.3 ltr
(right paddle in photo)
(paddle in centre is adjustable Ultra)
Just wanted to post in as I am a very big fan of this paddle..I am using the 'Ultra' smaller one as both my wave and race paddle. the difference between the Ultra and Elite surface areas and power is massive. Personally the Elite is too big for me. I am 88kg and 5'11'', I feel like my paddling strength is ok and i am on the board 5 days a week at minimum.
If your on the Elite already then the 2010 Naish Carbon or Carbon/Kevlar came in bigger blades (you will probably be looking for older models as the current trend is for smaller blade). DJ's points are very valid and the main reasoning why most companies are now reducing their overall blade surface area.
My personal suggestion would be to stick with what you have for a while longer. There is a lot of discussion about paddles/shaft length etc now days (which is all valid and important) but i was recently fortunate enough to spend a period paddling with Jamie Mitchell (10 X Molokai race winner) and Justin Holland (vice world SUP wave champ) at Australian Surfing Academy NSW. I was amazed at how much technique alterations changed the way your paddle actually feels in your hands, stride associated muscles and power that can be generated.
I hope this helps..good waves and clean water to you all..regards Nick
