I would go with the chronic, its name says it all, good yielder, great balanced high but leans more towards a cerebral feeling but its a tough decision between a few of those strains. If you've never tried sensi star then that would be a good one for sure, some of the best smoke around...the warlock and motavation both sound fun, never smoked anything from magus gentics or seen a grow of their gear, but it seems like people are big on that warlock...depending upon the pheno you end up getting of the sour kush that could end up being some absolute fire, bubba kush is maybe my favorite weed although its for sure couclock to the max so maybe not your cup of tea, but that should be a great cross and everything Ive had from DNA or Reserva Privada has always been good...that quad promo was bad ass, cant wait till they do another one that is similar, half the time Im a sucker for all of the monthly ones depending on the breeder that is offered. Peace and good luck, you cant go wrong, but I think my vote has to be the chronic, its some bad ass weed, which basicly anything from serious always is, peace brotha
