Ok... Here's the deal... I have been playing for about 1,5 years and I am completely selftaught... And I have some problems with my picking technique... I does'nt always pick up-down-up-down etc..
i.e. (d=downstroke, u=upstroke)

Most of the other guitarists I've seen play:
d u d u d u d u d u d u d u d
|-------------------12-14-15-------------------|
|----------12-14-15----------12-14-15----------|
|-12-14-15----------------------------12-14-15-|

I play:
d u d d u d d u d u d u u d u
|-------------------12-14-15-------------------|
|----------12-14-15----------12-14-15----------|
|-12-14-15----------------------------12-14-15-|

With this technique I have noticed that it is harder to keep the timing when playing at high speeds..

So...
Does anyone use the same technique as me?
Can anyone give me some hints or advices on improving while using this way of picking..?
Or
Shall I relearn it all?

Please help me since I don't know any other guitarist who can answer these question...
