It’s not an issue for every pick-slanter here… but a majority. I remember Troy talking about this as well… but he said he adjusted fairly quickly… but for me… it was a slow adjustment… much worse than I thought… it took over a year.
Tracking methods are diverse… but especially for pick-slanters… because they often have a linear 1 mechanic pick-stroke which frees up every other mechanics for tracking. Many develop tracking that integrates wrist deviation with elbow movement. Some use wrist-tracking exclusively (ie Yngie), which is why he can pick while playing behind his head. Some guitarists use their fingers for ‘reaching’ or for adjusting to wrist-tracking. Some use a combo of elbow, wrist, and thumb movement for tracking. The list goes on. All of these methods work fine for pick-slanting, because those tracking movements rarely interfere with their pick-stroke, again, because the pick-slanting stroke is typically linear, and only involves 1 (or maybe 2) mechanics.
However, X-picking can throw a monkey wrench into some of these tracking methods. The X-picking form typically requires multiple mechanics… sometimes working together, sometimes blending into one another. And the problem arises when the needed mechanics are already being used be the pick-slanter’s tracking mechanic.
On the other hand… someone who learned X-picking early-on… wouldnt run into this… if they started using tracking mechanics that interfered with their pick-stroke… they’d immediately feel it not working… and try something else.
My X-picking transformation was an extreme example of this. Mostly because my X-picking form uses every mechanic under the sun… and my previous tracking technique was occupying many of these mechanics. It would take a while to explain all the problems I had to overcome. But, on a positive note… I did overcome them… and I super happy with my current form. I’m a huge proponent of X-picking now.
