IIRC I got the Yngwie seminar first because I was by nature a DWPS guy. But of course I also wanted to do all the 2 way slanting too so next I got Antigravity and a while later I got Cascade.
love them all, well worth the $.
I didnt really learn them in any “linear” pattern. I think i had actually been doing some 2 way slanting on certain licks anyway so the 2 way stuff started coming along nicely and the strict Yngwie stuff felt weird. It felt weird to go from, say, g string down to D string with a DWPS downstroke lol. (outside picking to lower string in other words)
But then I also started getting my groove on a bit with the Yngwie vibe and now I just sort of have it all mish moshed together. Like, I have some decent descending runs worked out with either all UWPS or all DWPS and also can use 2 way alt picking.
The Yngwie “Black Star” style is still a bit weird for me. Id rather just pick every note one way or another. I can probably DO the escape hatch pull off but not if I think about it lol
Im also working pretty hard now on the cascade style Pent stuff and thats challenging to me because I never focused on it before. The first week I touched a guitar I started on modes and 3nps stuff so i kind of skipped pent stuff.
You may be like me. In my heart of hearts I would have felt limited if I stuck to ONLY DWPS…so it was a matter of time before I went ahead and got the Antigravity seminar and dove right in. At first it felt freaky to get the hand etc in the position to do UWPS lol. But now its cool because I can do ascending stuff with either 2 way alt picking or Yngwie style sweeping/economy
Id say go ahead and get the Antigravity. there is a ton of crossover IMO
Peace, JJ
