My 12" GSO has the same specs as you LB 12 cell, and the Bob's Knob's primary spring kit (and knobs) for you scope and mind are exactly the same. I have the Bob's Knobs primary springs and they work fine.

Despite this, and even if your springs were tighter, you still would probably find some collimation drift without the locking bolts. Even with the bolts, a bumpy car ride leads to the need to tweak things after re-assembly.

Any particular reason you want to forego using the locking bolts? Not that it's a critical feature, because a collimation fanatic will still feel compelled to make adjustment even using them....

Regards Peter
