I always just had way more of the standards than anything else, I guess because that was what was available more often than not, as well as them being cheaper in general.
For me personally, I am not worried by the height or weight of them, previously on 139s, then 144s when they came out but now 149s as my usual go to, even though I have some of every size on boards, as well as every option now too, standard, hollow cast, forged hollow, ti axle, almost all well used and traded in or bought on completes from ebay or private sellers, etc.
I have never bought anything other than standards from new, come to think of it.
The hollow axle / kingpin definitely had a few more issues with threading / stripping out, as well as the forged baseplate being impossible to get a broken kingpin out of when I did have to try, so there is that too.
In reality, the forged baseplate is too low for most of my preferred truck to wheel pairings, so I put a thin riser under them, but standards are fine as is, nothing else needed.
Others I skate with are all over the forged baseplate, ti axle, or at the very least hollow axle options and try to have the lowest and lightest setup they can, so for my overall group, I think more of those guys do go the forged hollow option, but many ride larger setups too, so I can see why lighter trucks on big boards work for them.
