The guy said that he thought the sand pull pro with the curb kit might be the cat's meow with his system
http://www.pavetech.com/newtools/curbKit.shtm Honestly, I think the Y pegs are great for patios, just not sure how they would work with walks. I install 90% of my walks with curves and am still trying to figure out how I could curve a straright peice of screed pipe around the curves.
BTW, if you were building a patio with the Y-pegs the guy said you could intall the pipes above the final grade and then create a T with 2 x 4's to screed the base. Just rip the part of the T that will be doing the screeding to the neccesary height for the base.
I'm looking forward to trying it out but frankly not sure what the results will be.
