here is my opinion.
If you builded a senior straight and thrue, you will be able to build the hog. There is some challenges in the box but if you had the patience to build the senior airframe it will be ok.
the astro hog is a very nice design and a great flyer, but it doesn't have the gentle flight of a pure second airplane like the four star.
If you want something diferent than a four star, I strongly suggest a VENTURE 60.
the venture 60 is designed by BRUCE THARPE, the designer of the four star 40 and 120
when Bruce left SIG, he created "bruce tharpe engineering" and designed the venture 60 wich is a "improved four star"
that's a wonderfull airplane.
the response of SIG has been to redesign the four star in a .60 size, but the four star 60 doesn't have the design improvement you can find in a venture 60

to me, the venture 60 is the ticket
