Piston wrist pin retainers!?!? Options

[stugray]

The new "spiroloc" wrist pin retainers as driving me insane!

I got the KB pistons from EMW and they come with the new fancy spirolocs for wrist pin retainers.

I just want some feedback about who thinks these are better than the plain old circlip retainer clips that come as stock.

IMO the older rings are MUCH easier to install and remove than the spirolocs.

I have spent an hour and many searches on the internet & youtube watching the spiroloc install but I still do not see how it can be done with the piston/cylinder up in the engine assembly.

AND I am planning ahead. Once I assemble everything & measure my deck height, I am expecting to have to take all of the pistons off.
Removing those spiroloc retainers looks like I will have caught turret's syndrome and ordered explosive devices online before removing just four of them.

What am I missing?!?

I stretch them about 3 inches. It makes the diameter smaller which aids the first half of installation. Then use a small screw driver to push the rest in. I use a small straight jewelers screwdriver like said before to lift up the notched end, then grab it with a small needle nose. They will pull out with a screwing motion easily.
