I totally agree that the springs on mass produced Newtonians should be replaced in order to maintain collimation. I bought the Bob’s Knobs replacement springs for my 8” dobsonian and the difference is obvious. It now holds its collimation and i very seldom need to make adjustment. The difference in the springs is obvious 



Oh yeah....the springs from Bob's Knobs are awesome

As a picture on this thread indicates the springs from Bob's Knobs are far superior to what comes on the GSO scopes no matter what name is on them.  I tossed my scope in the backseat of my truck, hauled it 15 miles and set it up to help with an outreach program and it was just barely out.  Bob's springs are well worth the money
