I'm 6'2" and have those 125mm triskates (powerslide V. vantablack). They feel too tall but not too tall to skate on, just uncomfortable for any movements that aren't marathon skating forward in a straight line.
I actually have a 110mm setup as well, kizer triskate frame on K2 unnatural boots. they feel a lot better height wise. they're also more fun to skate due to the shorter length, im less likely to accidentally clip my feet on crossovers. I wish I had more of a marathon boot setup with 110mm wheels because those k2 unnatural boots are super heavy, and feel completely stiff at the ankle. I'm sure they're great for jumping big gaps, but for long distance skating they feel like cinderblocks
I'm going to save up and buy the k2 r100 frame and try those out. I love the idea of 4 big wheels that can be rockered. I can't afford wizard frames but to be honest, if I hadn't bought all these different skates and instead saved up for wizards I could have afforded it. I just would have never known that its my ideal setup
