I say , suit yourself. Do what works for you and increases your enjoyment of this hobby.

An option that you may wish to consider is the use of mini-size rail buttons and a 20/20 rail. Many of my newer model rocket builds are getting these instead of launch lugs.

You can buy the rails from McMaster Carr.
