Inside Picking

Hey y'all, I hope all is well! I've attached two videos. I'm having trouble playing upstrokes when inside picking. It feels like my radial deviation is super limited and that i can't move it far enough to break through the string. You'll see this particularly during the licks at the end of each vid (the Pantera riff in the first one and a Charlie Christian arpeggio lick in the second). As for the 3NPS scalar playing, in addition to the above, it seems that sometimes I press against the string but don't go through it. Maybe it's a garage spikes issue? i also notice that the note quality itself is uneven; some ring true and some are less clear and so i’m not getting a smooth, obvious “going up and down a scale” sound. fyi I'm aware that I mainly have a DSX form when ascending a scale and then revert to USX when descending; it feels most comfortable this way for some reason. Not sure if these are all "inside/outside" picking issues but they’re issues nonetheless haha. but my main one is, like Zoolander, i can't seem to move left! Curious for your thoughts.
