if you can afford it, DJ shorts' purple colored grape krush sounds awesome. i'd like to breed that with a haze for a grapier haze.
color is more of a novelty to me, but on the flavor front, my two favorites are by DNA genetics
sweet haze - extra fruity, really sticky, & much better than average haze high as it has some real trippiness going on where a lot of hazes are more just clear headed and euphoric. it's ALMOST my favorite strain, but TGA's jack's cleaner 2 had a trippier buzz with a really cool touchy feely aspect i've only experience once before with short stuff's onyx. that one tastes nasty to me, but the buzz is awesome
sour cream - a little too stony for me, but at least not KO stony, but it has a really cool slightly sweet & fruity cream cheese flavor that's very classy.
i bet sannies' chocolate rain is pretty good as his gear has a lot of universal love for quality across the board. i can't remember any other flavor strains he has, but if he does, i'd bet those are great too.
if you ask me, DJ short's blueberry is overrated. it's stony like skunk #1 which i don't like, and the two times i've scored some, it was underwhelming tasting. it was exactly like having a single grain of artificially flavored blueberry sugar on your tongue. a lot of hazes are fruitier than that.
i've also tasted more authentic flavors like pineapple in a bud i scored once, lavender *BLECH* it's like taking a bath in perfume, diesel (onyx) yuck again there... it's a flavor only a gearhead could love, crushed red pepper in ORIGINAL kali mist which is now just fruity & spicy and one of the most authentic flavors of all... licorice in durban poison. not my thing at all, but it's very convincing.
you might want to look into the effects of lighting on flavor too as i got a very grapey taste out of my super cali haze freebie with hints of grape too from my joey weed C99s under a halide, but when i grew the cross of the two i made out under a sodium, i got more of a generic fruity flavor. my handle's a tribute to how apeshit i went when i tasted the super cali the first time and it tasted like straight up grape juice. maybe the two times i tried blueberry, it was grown under sodiums too. when i get the chance, i want to compare the effects of each light type on clones for both flavor & THC profiles. i'm not sold on sodiums yet.
