Absolutely. But you can't fairly compare tomatoes with, I don't know, apples? I'm just saying a mini of the same series will be lighter. It's good of you to make the distinction, though, as the OP may not know that.

As far as what I have:
OnGuard Brute - Seems strong. Very heavy. Rarely use it. No problem finding things to lock to. But unless I remove the front wheel, per the linked instructions above, it has a big gap.
OnGuard Bulldog Mini - Great little lock. Small, but heavy for the size. Heavy because it's strong, and light compared to a similar, but larger, lock.
Kryptonite Kryptolok Series 2 Mini - This lock I really like. All it said on the packaging was what I wrote in the description. I don't know if they made a real 'mini' mini with that series, or what, but this one has a 7 inch shackle, which is longer than most mini's that I've seen. This one seems strong enough, big enough for most applications, and not too terribly heavy. Really like this lock.

Some great advice above as well. When I first started cycling, I figured someone had already found the perfect lock, and I would buy that. After reading many, many posts and reviews, I've decided that everyone's application is different, which makes it tough. I do think you can make what you have work for you though, in probably all but the highest crime areas. Then, IMHO, nothing will save you if they want it.

Long post. Up late and bored. Nite all
