It's not that hard to do. Videos on youtube get you through it. I don't always think it's worth the time. If you really think it's too slack right now than do it. Otherwise maybe a little less air will give you the sag you want. With the Reba quite often you can boost up the negative chamber a bit.
It's not your strength or skill. It's your level of commitment.
