Easy, the GS..... You could ride that every day of the month. There would be at least 4 days a month you couldn't ride the other one, cos the painters would be in. You'd loose another few days cos you "rode it" the day before. Then there would always be the days you really, really want to go for a ride and its just not interested or, it won't start..
The GS would never moan when you wanted to go up the dirt track... Some like to, off road!
Oh, and I've let a couple of mates have a go on my GS, their wives knew and were happy, could you share the other one.....(would you want too)..
The only upside, I guess is, you can't ride the GS when ya pissed! And I wouldn't mine giving that a thrashing the a good rub down with a damp cloth!!
Oh and the GS is blue.... Red is better at blow jobs!
And I wonder which one is more expensive !
