the boiling thing only works if you put them back in and skate the trucks immediately. it doesn't make them much softer but helps with the breaking in process. this is unnecessary if you live in a considerably hot environment or just have enough patience.
i ended up just skating my new ventures as it is. they are totally fine and ride as expected now. feels less dorky than riding indys, but i can take almost the same turns.
but check this:
i was skating a friends 12 year old cruiser board today, which was equipped with hurricanes, of all trucks. nevertheless that thing turned sharp as hell. he said there were some aftermarket bushings in them but he couldn't remember which ones, but they weren't bones. anyways, those trucks, which i initially mistook for destructos for some reason(probably cause they actually turned), were super fun to ride. there were some stereo cruiser wheels about 58 mm on this board and the trucks were mounted on some fat ass risers, so you could really lean in.
not sure what to think of this tbh. lots of peers had hurricane trucks back when i started skating back then, but we would ride our trucks tight as fuck, too. it was cool tho.
