Sativa will give you head high when its mature and indica will lay you out when mature. The high has to do with the strain not the trichomes you get higher if you let it go longer because it produces more trichomes in its final weeks.
Each strain is different some strains trichomes will never amber they will stay clear and cloudy even when fully matured. Dont look at trichomes for the type of high you want look at the hole plant watch until it looks mature.
Going off trichomes is kinda win/loose because while some say pick right when you see amber (because amber means degrading"fact") but also if the strain is producing more trichomes per day then what is turning amber its not done.
Its kinda a math game once you see 10% amber thats you sign degradation is happening faster then the plant is producing more to take their place.
Its hard to explain if you want me to in detail I will
