I'd just run it how it comes also, if you decide you "need" a trigger later I'd go the rvb route or have our resident glock trigger guy give it a working over.
There aint a lot of magic in them. I had a good buddy years ago and he sold a bunch of the kits he made and they were very well received. He used to change one of the springs for an extra power and one for a reduced power, but now I don't recall which was which. Aside from that just polish up the parts that contact each other and thats about it. They can be done rather nicely. Both of my 34s are around the 2 pound mark and break nicely for what they are.
