have a wraith spawn and I getting ready to upgrade and bullet proof it. I am looking into the draglinks and tie rods to upgrade an alloy/metal and noticed that I see some options give you the links in ally/metal but you use plastic ends. there are others that the whole link is solid and has the ends made into it. so what is the advantage of getting a alloy/metal rod if the ends have a chance to break. I know coming from nitro tmax that is fully alloy frame that leaving some things to plastic parts seems to be more flexible and breakable that will save some more expensive parts from bending breaking. was just wondering if I should get the links that have the ends made/casted as one piece to link which looks like a little more expensive or get the ones that have the removable ends. was wondering what others thought for I have not found anybody say pro or cons on one piece links vs links with removable ends. any advise would be great
