55 are really good for dj if you have them set up right and if you watch the nissan qashqai paul bas uses all mountain 1s lowered to like 100mm big fors are sometimes just as good
and if you do want sommit like 120 or 140 for big drop or north shore 55 or whatever have alot more travle than dj1s or 4x that ony have 100 travle and cant be ajusted
but if you are good enough it wont matter about the weight look at darren baracloth and paul bas they use 55 lowered and look what they are can do on them
