I feel for you on the whole weather thing.
I live in Southern California, and weather usually isn't a problem down here.
I never got a 705.
I got the original Impulse, then an Impulse Pro.
I was going to get a 705, but my wife got me my 1/8.
I knew she wouldn't let me spend money on the 705, so I started running the 1/8 more than my Impulse.
When I wanted to get back into touring cars, I wanted something different.
I was thinking of getting a G4 or a 705.
The G4 was different than other cars out at the time.
The 705's design wasn't too much different than my Impulses.
I'm glad I didn't get either car.
That's when I found out about Serpent coming out with the 710.
