Which trucks if any do you think would put less stress on your legs? Maybe make your legs less tired?
What are you skating? Flat ground, street, parks, ramps?
The combination of trucks and how steep a board is can definitely have an effect, as per some of the more interesting videos from people on youtube and the like.
Steeper kicks and longer wheelbase trucks can mean you will get more height from your ollie, but you have to put more effort into getting it there, which could make your legs more tired.
More mellow boards with trucks that extend the wheelbase the least are way easier to pop but you are going to get less height, but might be easier to skate for longer or put less stress on your legs.
In order of shortest to longest wheelbase from the big brands, Ace, Indy, Thunder, Venture, but then it really comes down to the board as well, how many fingers of flat - distance between bolts and start of kicks - so no fingers of flat and steeper, boards are going to be very heavy feeling to pop, but then too many fingers of flat or very mellow and boards are going to be very light to pop.
Combinations of these will very much make a board heavier or lighter to pop, eg putting Ventures on a very mellow board with a short wheelbase and a lot of flat before the kicks will still make it very light to pop.
Last but not least, the legs themselves - warmups or fitness levels, tightness of trucks, strength of ankles, calves, etc all play a big part in it too.
