Sold both my saddles and bought an Ergo yesterday. Got to mess around for a few minutes today and it is the most amazing pice of climbing gear I've ever come across. Who else loves their ergo?
Never tried on the Spartan but looked at it many many times before biting the bullet on the Ergovation. Rode a Edge for awhile which is the same as the light but not sure how they compare to the Spartan.
I got the Ergovation Economy (the regular one was a little too much for starting out with) and love it!
Especially like how the leg padding is adjustable. Excellent piece for the money!
Got to finally do some work in my Ergo yesterday pruning a couple big maples and man this saddle is awesome. Everybody claims it to be bulky and heavy but I didn't even notice it was on really.
