You can do a double on the ramp by doing a start jump> pre the ramp (which is very tight)> do the normal jump where you hit the walldouble well>rampdouble and then you can probably wallshot to the end using the second wall.
The only thing is that the pre you shoot is a bit too tight (not much timespan you can shoot it). So making it a bit easier to shoot that pre would be nice
other than that I really like the strat!
