I see what you are saying. ^_^ And I am practicing those techniques as well as my normal technique. Some of the new moves I am working on is coming along very well. The double thumbing is being a problem. LOL I seem to be able to double thumb going up (GDAE) and have worked on better sound/strength on the upstroke, but I can't seem to go down the strings (EADG) worth a darn for some reason! I also noticed that double thumbing is a lot like this one weird move I do with my index finger (sometimes my middle finger), I can relax the first joint in that finger and double hit the string not too unlike double thumbing. So with that in mind I actually purposely set out to double 'thumb' with my index finger and it didnt work out too bad. It IS hard to add another plucking finger into the mix like that but right now I am exploring all ways of using the right hand on the board.
My right hand technique used to be pick only and then pick and 2nd and 3rd finger plucking with it (what I was always told was hybrid picking)...then when I got back into playing after being out of it for several years I went straight to plucking only. My style there has been 2 finger, 3 finger, something all 4...whichever -- my plucking style has been rather 'loose' I guess but it works for me.
I read threads here on technique and pay attention to things said and such. I am very eager to learn new things on the bass, I will even try things that most will say is a no-no just to see why its considered a no-no. LOL I was reading the latest thread on Cliff Burtons style and someone described how he always rested the palm of his right hand on the board but it was 'wrong' technique. Okay.... so... I tried it anyway

...You know what, resting the palm of my plucking hand on the body actually works really cool for /me/. LOL I cant see why its considered wrong. Well I can but if your fingers are long enough I don't see it as 'wrong'. I also will straighten my pinky out sometimes and have it on the board as an anchor too when I pluck. OOooo I guess thats wrong too? I have to wonder how what works for someone be considered 'bad technique'? But thats another subject.
Anyway, I was given a link to a Sheehan solo and thats what really opened my eyes to just how far you can go with right hand technique. I was floored watching him. I have so wanted to be able to break loose on a bass LIKE THAT!!! Some people call him a 'wanker' for some of his style? What??? My first thought on that is the ones that cut him down for that are ticked cause /they/ cant do it is what I think. So as stated above, a friend took several vids from youtube, burned them and sent them to me. Included in that was several Sheehan lessons. I watched one and was amazed that some of his left hand technique I ALREADY DO!!!!!!!!! At least one of his 'economy of motion' techniques I have done now for awhile and I find it cool that at least one other bass player figured one trick out too
I am seriously going to pick up some Sheehan books and vids as well as Wooten (if he has any out). I never had any influence the first time I played, not even the one that inspired me to take the bass up (Gene Simmons). All kidding aside, Simmons is not a bad bass player. But, hes too cut and dry, too 'normal', he doesn't push the envelope. He works the bass too mundane to be honest. I know several of his pieces for KISS. They are not bad actually. God of Thunder has a great bass riff and it was the ONLY thing I could remember to play when I picked the bass back up. LOL
I wonder, has anyone else been inspired to pick up bass because of one artist yet never took any more influence from said inspiration?
