I feel that yes they will help short term but in my view they can become a crutch that you don't really need. I almost relied on my 15's to fly in light winds until the day I didn't have them. Set your kite up, and your leaders and use your 13's. Footwork and body usage will serve you better than different handles as this skill will transfer to all the different sail configurations.
