Should I keep running my old projects as Active, Or just Verify

Greetings, friends.
Wondering if I should keep running some of my oldest set of GSA projects as active…and not just set to Verify only…
I mean those oldest projects where I just link to my money site directly with SER.
I don’t think I need to stop running old projects where SER creates links at T2 T3 .. .. just those pointing RIGHT at the  money site.
…and JUST those projects, of course, that I have newer replacements for with my own T1s, either on PBNs, a few legit listings, and various social media and other content platforms, and hopefully some authority links.
Is it ever OK to link directly to a money site with SER?
I have Asia Virtual Solutions active, blog comment, directory, forum, guestbook,Image COntent, Microblog, Pingback, Referrer, RSS, Social Bookmarks, Trackbacks, Web 2.0, Wiki running.
I also have a separate set of older projects that post to anything that will accept an article pointing at the money site. The articles are OK. Spun, hand-written, reviewed spintax for accuracy. On those I have Asia Virtual Solutions (projects to MS that use articles), articles, blog comments, pingbacks,referrers, social bookmarks, social networks, and wikis that use articles when posting.
This is how I chose to set up older projects. Are *either* the first set of projects, or the second that use articles,  appropriate as a T1 pointing at  a money site? And if not, what SHOULD I be using SER-generated backlinks? I’m *SURE* some will suggest SEREngines. I’ve haven’t used SEREngines since the last version, so if someone could explain I would very much appreciate it. Trying to do SEO right, finally. No more continuing poor practices that are just from a time I didn’t know better.
Should I *NOT* have been doing this? Is it considered “spam practices” by Google? At some point, I came to to understand that T1s should be stable and basically be legit. Is it OK?
