I switched from St Croixs to Powells last year. (not a dis to St Croix, cause they are obviously awesome rods) However I prefer the Powells because they are extremely light weight and balanced perfectly. Due to them being a CA company they are, as you have found out, not known about up here too well compared to St Croix.
Like said above, they are a bass series or rods, but Im sure the spinning rods can be adapted to your walleye needs, unless you don’t want an extra fast action.
Lifetime warranty on all rods is a plus, although I have yet to have to use it. And my customer service experience has always been great.
Only negative is that the blanks are crafted overseas which is an important factor to some folks.
