BGS holders

[vintagebaseballcardguy]

I don't follow TPGing as much as I used to, and I have a couple of questions about the different iterations of BGS holders over the years. I thought this would be an easy Google search, but I didn't find what I was searching for. I know PSA has gone from no hologram to hologram to lighthouse, but I don't know as much about BGS.

Are the older BGS holders the ones with the four sub grades, and have those older holders been more or less likely to hold trimmed cards of any significant player (all the way from Cobb to Trout)? Or has BGS had problems detecting trims throughout, thus nullifying any concern over which type of BGS holder one's card resides in?

Thanks in advance. I am genuinely curious as to your observations, as I see cards in BGS holders with the four sub grades and holders with no sub grades.
