Hi-Lo Chassis on Coverted Skates?

[tubby34]

Does anyone use a Hi-Lo Chassis on converted skates? I recently made a change to get a taller wheel, and this weekend I felt like I was "Slipping on a Banana Peel", even fell about 6 or 8 times backward.

I previously used the Tour goalie skates with a 59MM 5 wheel chasis.

This weekend I was in a Mission Hi-Low Chassis on a Cowlingless Bauer Skate, 72MM across (couldnt find 68mm on short notice for a tournament).

How should I choose the wheels?

68MM, 68MM, 68MM, 68MM (I have this setup outdoors and slip out too)

72mm, 72mm, 72mm, 72mm (I liked the height indoors for mobility)

68MM, 68mm, 72mm, 72mm - Using the hi-lo chassis, im afraid going to one size wheel might be the reason, the 3rd wheel only touches with my weight in.

Lookign for suggestions after 15 years in the 47mm/59mm hell.
