Looking for suspension suggestions

[Thealien]

I have a 2 wheel drive 1972 Blazer with a tired and worn out suspension. In the coming months I am having body work done due to some rust issues. At that time I will be addressing the suspension and an LS swap. I plan on stock ride height, not lowered. Maybe just level.

I have been suggested to go with a 4 link over the factory trailing arm suspension. I had always heard the trailing arm suspension is pretty good and can be improved on. I will not be tracking my Blazer but will be doing spirited rides in the new Hampshire mountains, the Kangamangus highway etc.

I am looking for good ride quality and an increased handling. Pros and cons? Suggestions?

Thanks
Mark
