Hi Dean, I am around the 100kg i own the 27" Ace and find it comfortable in most conditions, i also brought the 25" Ace to eventually use in flat water i can paddle the 25" in flat conditions and small wind chop with no problem but not sure how i would go in race conditions with all that water moving around from everybody at the start. and my wife won't give back the 25" Ace thats the main reason i stay on the 27"
