Hi Nacho; Building my own board since i was a kid( for 46 years by now) to fit my home spot which is beach break I keep on catching influences from reading Seabreezers post. Out of buying anyone, I did have the same thoughts of choice about those two boards as you Nacho. Still Raptor from Naish and its ancestor which is the one with 4channels built few years ago are both the single kind NAISH model making me " froth" about .Despite of she got the Naish shaping touch from getting balance forward stance at nose buoyancy of the board.
And obviously this buyoancy balance is why i would prefer Hypernut mainly for reasons as said by Marco Gribi in this topic:
www.seabreeze.com.au/forums/Stand-Up-Paddle/Review/Starboard-Hyper-Nut-Minion-Vanguard-MPH/?page=2&index=51 and specially this mention about the Hypernut "
One other factor that helps with wave entry is the wider tails as they tend to get earlier lift from the coming wave and then they slip down the wave with quicker acceleration followed by drive from the quad fins." I think this is why i like Hypernut rather than Raptor is the fast entry. In second reason of my Hypernut preference more than Vangard principle is the common shaping one shared with MEYERHOFFER board . IMO those MEYERHOFFER are really up to date

Out of what did i say here, Hypdernut or Raptor dont get enough buoyancy ranges, should cover every 10 kg of weight . So catching influences as i explained up here I drawn something fitting to >70 and <80kg as our range of weight.
So this is my idea about it , I called it " Manix"

Take care watching the buoyancy diagram . Please note the equal balance of volume between tail and nose as well as center sections of the board. This is the" S" outline effect before other shaping components... Also this "S " or depress curved outline has many others reasons i cant explain here by now.
You cant have this perfect volume balance on Vangard style and more on Raptor where balance is pull on nose with such narrow tail able to dig rails and fins
Yes this board got a nose riding option
