I didnt know where else to post this so i decided to go here

im in the midst of learning the shredding portion of vela, together we await the storm. and i find it really hard to slide from the first sweep riff up to fret 17 any tips to help me?? or in any case, help on the whole riff all together??
it's hard but it just takes a lot of practice... i still haven't even got it down... =\
