Michael,

I am planning to buy Sprys.  His are differentiated by their failure
mode.  That is, with the external spring they'll still have a little
function if the oleo goes flat (and vice versa).  I've heard of two
situations that Ong's have failed.  I know of no major adverse affect
but find comfort in having at least half a strut for landing.

Cheaper too.

Larry
