I've been practicing 3 finger for about 5-6 years. I can make steady even sound until 150 bpm but after that speed, it was always difficult for me to avoid that galloping or fast triplet sound. Maybe my brain rejected recognizing 3 finger into 16 beat. I uploaded one of my cover below. I practiced that song for years and years but still not very satisfied with the result. IIRC, that song's bpm is 175.
After that song, I tried other patterns too. My basic pattern is 3213-2132-1321 but I also practiced 3212-3212 and 3121-3121 to find my best pattern. Hmm.. all those patterns were not comfortable for me. It saves my stamina but it is really hard for me to keep accuracy.
Currently, I am practicing Iron Maiden's Run to The Hills and I found playing that tune with 2 finger can be more comfortable than 3 finger. Galloping with 2 finger is confusing but I think I can manage that. Also 2 finger's tone is much consistent than 3. So I tried other bpms like 140, 150, and there were some stamina and accuracy problems but 2 finger definitely lessened my brain's stress.
I am on the verge of letting 3 finger go. It may need much time for me to achieve high speed with much stamina. But it will help me play any line I want especially when improvising or soloing. One thing that holds me back is getting speed more than 200 bpm... but because 3 finger couldn't achieve that speed, that will be no reason for me to choose 3 finger.
So one thing I learned from this 6 years.. is that 3 finger does not guarantee faster speed. If there are some metal/jazz bassists who use 2 finger in super high speed, please let me know. My goal became playing bass solo of Dream Theater's The Dance of Eternity with two finger.
