Filco caps don't suck for everyone. I do, however, hate them.
by double shots you mean from signature plastics? or used cherry corp caps?
given that there is moogle kit group buy going on atm, you should go for cherry crop doubles
for the shear thickness cherry corp doubles got.
PBT caps is also an option. Some prefer it over double shots, coz double shots use ABS plastic. Despite legends stay in place for a long time, the cap would still get shiny fairly quickly (like any other ABS keys). PBT on the other hand can retain the texture for much longer.
