Hm... My "technique" is probably something like this.
Any given solve:
Cross on B, U, or F, depending on the situation
F2L inspection during all of cross
Intuitive/algorithmic F2L (you heard me right)
24 OLLs
Full PLL
Other:
LL edge control
Some of the Winter Variation
A little multislotting
A bit of force OLL skip stuff
And as for my style... hard to say. I use some very extravagant, flashy, open, smooth finger tricks. Some may even say... outlandish? risky? only loosely feasible?
EDIT: I average at 17.61 and my PB is 15.06, and yes, I am also thirteen.
