Why would you avoid LLL? I've never bought from them so I'm curious why you say to avoid them.
I'm also confused about your pastel. You seem to switch back and forth between him being a possible het and a het. If he was sold as a het albino then he's a het until you prove him not to be het. If you are considering him a possible het because you don't trust the seller then he's still a het until proven otherwise. If he was sold as a possible het (50%/66% or some other number) then he's a possible het until you prove him to be a het.
If you want to work on producing pastel albinos then buy a visual albino female, don't get a spider or pinstripe female.
Everyone likes something different. I love bumble bees and that's why I have 2 in my collection, but they are also something I have plans for in terms of breeding (enchi bumble bees, killer bees and killer bellies). You need to make sure you are producing babies you wouldn't mind keeping if they don't sell. If you don't like Lemonblasts or Bumble Bees don't buy a pinstripe or a spider.
