Be careful in the wiggles if you make a high-frequency trace turn parallel to itself that those parallel sections are at least separated by a distance of 4*trace width=20mil.
yyehhh it's a bitch doing these by hand.
I painted the likely problematic edges with red and circled in green the wiggle you created with a geometry that completely avoids the problem.
yehyeh thank you for that, makes it really clear. the thing is there's really not a lot of space, in which we need to get rid of about... i think it's something like almost 0.8mm length discrepancy: difference between two BGA pads *and* the right-angle turn. the toradex-recommended wiggle method is fine for compensating for a single 45 degree turn (found that out a few weeks back, now) but for the amount of length discrepancy here it would be something like... maybe... eight or nine toradex-style wiggles.
i'll see how it looks.
