Rumor has it that Krux are based off Stage II Indys - having skated every stage and own XI and Krux, they feeling is soo similar, yet Krux, like ACE, are snappier with turns compared to Indy. My only issue with all three is they feel so high (I like Thunder height). Regular Krux are lighter than Indys and arguably turn just as well (their pivot cups are a little odd, they are really deep and deform oddly, like the turn is very side to side); cheaper too. Throw in the downlow pin and they are lighter than TI Indys.
I watched the Bondi event last night; everyone was riding indy except for McClain and maybe one or two others?
Tons of dudes ride Thunders that shred bowls, Cody lockwood, the Millers, Perelson.
