I really like stinky males, the resin thing hasn't been too big of a difference from what I've seen in my small bit of experiences.
Say I had two males 1 stinky/smell you're hoping is expressed from that particular cross and 1 male no smell but some resin, I'm going with the stinky male. That is if all other areas are similar ie structure, reliance etc.
I'm with you, it's harder to get the smell and taste right (the two go hand in hand) than it is to get frosty plants. It used to be the other way around, but not anymore. We used to have to search through a shit ton of males to get just one that would put off frosty offspring and that made smell secondary, if smell and taste were good then cool but if not no big deal, you had to have the frost and that used to be a lot harder to come by. I don't care how good something smells if it doesn't frost up it's not going to be that great. Now we have the luxury of, for the most part, taking the frost for granted and zeroing in on flavor and smell. Think about it this way; Maybe the difference today would be between having a 25% plant vs a 20% plant by picking just for the frost on the male and that's a 50/50 chance right? Back then the wrong male could be the difference between 3% and 15% offspring.
You get frost with almost all males that come from good modern poly-hybrid strains, maybe more, maybe less but it's there. Guys used to search through Hundreds of males to find one that would reliably put out frosty offspring. It was also a much bigger difference between having a killer male and just picking any random male. A random male from today's poly-hybrids is going to have at least somewhat frosty offrspring, back then a random male might put out freaking hemp. This is also a reason why I'm not in a big hurry to start over with landrace strains. Anyone who tells you it's as easy to find a good male from landrace strains hasn't worked with them much or is able to pick from way more plants than I can now that I'm all legal beagle. Even if I get a license for 150 plants that not enough to really work with new landrace strains and do it right.
Another thing is that if I add a funky smell or taste to my strain line I'll end up tossing that whole line. I can get the frost back but sometimes that freaking smell is hard to get out. I worked with a Black Russian male for a while that put off amazing frosted humoongoussss buds, it ate nitrogen like it was candy. Sadly it didn't matter what I crossed it with they all smelled like Black Russian and I was so sick of that smell after having so much of it to smoke that I wished I hadn't grown them. Friends still loved em and they grew like crazy but I'm done with all of that line. That experience made me way more picky about smell than I had been before.
When there's fire all over you don't have to look that hard to find it, special flavors and tastes are what sets lines apart now, sure they have to be frosty but like I said, frost is a lot easier to find today than back in the day. Unless you are just working for frost, then I guess it's all that matters, but not to me, not even close.
