Buggy here, too!
No question. I don't own a Truggy myself but I've driven a friend's RC8T a few times. Very nice handling, very easy to drive (fast) but after some time I start missing my agile and nimble RC8B buggy.
IMHO driving a Truggy is too simple - compared to racing Buggy.
But I have to admit it's still LOADS of fun!
