Another possible option
Some years ago when 10 speed was first coming into age, a company named IRD (Interloc Racing) made a Campy compatible chain link that allowed easy chain installation and removal. The "Snap-Link II". You used this link instead of the hassle of making a permanent pin placement.... you may remember the (IMO) stupid vise grip like pliers needed to install the pin... I have this tool around somewhere...never found another use for it.... cost $$$$ too.
But, using the Snap-Link II was a no brainer...no more fear of the chain coming apart.
I do not know if IRD still exists.
HOWEVER, when KMC introduced their Campy compatible 10 speed chain, I switched over to their chain and have NEVER looked back. Excellent chains:
low noise, long wear, excellent shifting, less costly...I have nothing bad to say about this chain.
