suntour forks are good naman and it can take a lot of punishment and can even stand higher drops than a regular person's heart can take but ive seen a newbie break his new suntour fork (as in new, he just installed it the night before) on the AFP racetrack, he hit a very steep incline without pulling up so the fork bent inward and off he went flying
you got 3 suntour forks right? 3 x 3000 can get you a very good marzocchi fork na
im not saying na dont get a suntour fork, if your play is xc/trail riding then go get one because its a bang for buck fork and will perform almost as great as those more expensive forks. im just pointing out na you have to buy the right equipment for the right job, if you're into FR and DH then its better to invest in a more expensive fork because it'll be safer and more economical in the long run since it can soak up more punishment thus will last longer, anyway this is just my 2 cents... its still up to you who'll be the buyer and user ;)
