If you could handle the Pulse, the SSE would be a logical step and a good choice.

I've owned both a kit and an ARF version. Both are great.

The quality of the kit I built was outstanding. The wood quality was excellent, the laser cutting was clean and accurate, the instructions and plans were great and the design made for quick, easy assembly. Sig kits are top-shelf in my opinion.

As for flight, I've never flown a Pulse but I imagine it is a nice flying sport type plane. The SSE will probably be a lot snappier with a faster roll rate and quicker maneuvers with controls throws set at high deflection. Keeping it on low rates though, it can be fairly tame. Point the SSE in a direction and it will fly there. The down side to that is that it will fly right to the ground if you happen to point it that way. The SSE will also slow down and land fairly gently, maybe not trainer like but still nothing scary. It's just an honest, simple, fun airplane.

I say go for it.
