One upside to going through so many guitars as you learn is that often you'll improve certain techniques as you take advantage of each guitar's strengths. Shorter scale guitars helped my stretches, my radiused fretboard on my Navarro improved my barres and I found new tone colors too, my long sustaining Huipe "Bouchet" improved my muting. I think it always helps to be quickly rewarded when learning new techniques.
