I worked on these G perms for ages, trying several different fingerings from different vids. I wanted to avoid rotations so focused on the wide F turns and similar. When done exactly right they flowed OK, but I found them unforgiving and too easy to screw up, with all the fiddly tricks in there. So I use 15-move algs in <RUD> and for me they work better.
It's all personal preference of course, but still I'm surprised the easier algs aren't more widely used and more widely listed on sites like BM's.
yes personal preference, because i tend to dislike RUD algs idk why
well one of the great things about G perm is it's only 12 HTM or 13 QTM, quite short, so you can slow down a bit and it won't really affect your speed.
and trust me, i didn't get G perms naturally either. but now they're among my favourite PLLs! i never watched any videos or anything, i just thought real hard about the alg, and with some testing, i made up my own finger trick. i've never seen anyone use my finger trick before (cause i don't watch a lot of videos), but i'm sure someone does.
for example, R2 u' R U' R U R' u R2 y R U' R'
R2 u' R U' - very straightforward, R2 goes downwards
R U R' - don't regrip even until now, the U turn should be with a flexible right hand, quite free until now because that's the first right handed U-turn.
u R2 y - as you finished the R', slide in a reverse-lefty wide u (index finger from FL to LB) and finish with R2 upwards as you rotate
R U' R' - your right hand shouldn't have to move much to set up for this one.
